Abstract
Studying polymer micelle structure and loading dynamics under environmental conditions is critical for nanocarrier applications but challenging due to a lack of in situ nanoprobes. Here, the structure and loading of amphiphilic polyelectrolyte copolymer micelles, formed by 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and n-dodecyl acrylamide (DDAM), were investigated using a multimodal approach centered around in situ resonant soft X-ray scattering (RSoXS). We observe aqueous micelles formed from polymers of wide-ranging molecular weights and aqueous concentrations. Despite no measurable critical micelle concentration (CMC), structural analyses point toward multimeric structures for most molecular weights, with the lowest molecular weight micelles containing mixed coronas and forming loose micelle clusters that enhance hydrocarbon uptake. The sizes of the micelle substructures are independent of both the concentration and molecular weight. Combining these results with a measured molecular weight-invariant surface charge and zeta potential strengthens the link between the nanoparticle size and ionic charge in solution that governs the polysoap micelle structure. Such control would be critical for nanocarrier applications, such as drug delivery and water remediation.

Abstract
The interaction of hydrophobically randomly modified and end-modified poly(2-(acrylamido)-2-methylpropanesulfonate)s (PAMPSs) with nonionic and positively and negatively charged surfactants was studied with the fluorescence spectroscopic technique of labeled pyrene. The results indicated that the randomly modified PAMPS bound to the nonionic and positively charged surfactants and that the disruption of intrapolymer micelles formed by the polymer occurred. In contrast, end-modified PAMPS was bound to the surfactants without the disruption of multipolymer aggregates formed by the polymer in a comparably low concentration range of surfactants. The conformation of the polymer-surfactant complex was confirmed to depend on the position of the hydrophobic group in the polymer chains. In the case of negatively charged surfactant, the complex formation between the polymers and the surfactants was significantly restricted due to the electrostatic repulsion of anionic sites of the polymer chains and the negatively charged surfactants.

Abstract
Amphiphilic block or graft copolymers have been demonstrated to form a variety of self-assembled nano/microstructures in selective solvents. In this study, the self-association behavior of biodegradable graft copolymers composed of poly(γ-glutamic acid) (γ-PGA) as the hydrophilic segment and L-phenylalanine (Phe) as the hydrophobic segment in aqueous solution was investigated. The association behavior and unimer nanoparticle formation of these γ-PGA-graft-Phe (γ-PGA-Phe) copolymers in aqueous solution were characterized with a focus on the effect of the Phe grafting degree on the intra- and interpolymer association of γ-PGA-Phe. The particle size and number of polymer aggregates (N(agg)) in one particle of the γ-PGA-Phe depended on the Phe grafting degree. The size of γ-PGA-Phe with 12, 27, 35, or 42% Phe grafting (γ-PGA-Phe-12, -27, -35, or -42) was about 8-14 nm and the N(agg) was about 1, supporting the presence of a unimolecular graft copolymer in PBS. The pyrene fluorescence data indicated that γ-PGA-Phe-35 and -42 have hydrophobic domains formed by the intrapolymer association of Phe attached to γ-PGA. These results suggest that the Phe grafting degree is critical to the association behavior of γ-PGA-Phe and that γ-PGA-Phe-35 and -42 could form unimer nanoparticles. Moreover, when γ-PGA-Phe-42 dissolved in DMSO was added to various concentrations of NaCl solution, the particle size and N(agg) could be easily controlled by changing the NaCl concentration during the formation of the particles. These results suggest that biodegradable γ-PGA-Phe is useful for the fabrication of very small nanoparticles. It is expected that γ-PGA-Phe nanoparticles, including unimer particles, will have great potential as multifunctional carriers for pharmaceutical and biomedical applications, such as drug and vaccine delivery systems.

Abstract
Receptor-binding peptides are suitable targeting moieties for macromolecular therapeutics. Binding several targeting peptides to one macromolecule may improve biorecognition due to the multivalency effect. On the other hand, the resulting amphipathic structure of such conjugates may result in the association of side-chains with a concomitant decrease in the accessibility of the side-chain-bound ligands. Using the one-bead one-compound combinatorial method, we have recently identified a heptapeptide (YILIHRN; HP) ligand for the CD21 receptor (Biomacromolecules 7, 3037, 2006). Here, we evaluated the relationship between structure and self-association of N-(2-hydroxypropyl)methacrylamide (HPMA) copolymer-HP conjugates using fluorescence resonance energy transfer (FRET) to evaluate their conformation in solution. In addition to HP, HPMA copolymers containing side-chains terminating in tryptophan (energy donor) and dansyl (energy acceptor) were synthesized, and solutions were evaluated using an excitation wavelength of 295 nm (ratio of emission intensity 510 nm/370 nm indicated energy transfer efficiency). It was found that higher HP content correlated with higher FRET efficiency, indicating the formation of compact coils. Modification of the HPMA copolymer backbone by the incorporation of acrylic acid (AA) comonomer units resulted in decreased FRET efficiency, presumably due to the expansion of the polymer coils as a result of electrostatic repulsion. The dependence of FRET efficiency on pH was in agreement with the ionization profile of the AA residues. To determine the effect of HP content on enzymatic drug release kinetics, HPMA copolymer-HP conjugates containing GFLG side-chains terminating with doxorubicin (DOX) were incubated with papain and the release of free DOX monitored. When HP content increased above a particular threshold, the rate of DOX release decreased as a result of self-association of HPMA copolymer-GFLG-DOX-HP conjugates. The FRET data correlated well with hydrodynamic volumes determined by size exclusion chromatography (SEC), with molecular weights determined by light scattering, and with the kinetics of drug release.

Abstract
Cholesterol mesogen containing monomer, cholesteryl acrylamido butyrate (CAB) with the novel spacer group drawn from 4-amino butyric acid has been demonstrated to exhibit good reactivity with 2-acrylamido-2-methyl-1-propane sulfonic acid (AMPS) to yield copolymers with CAB content as high as 15 mol % hitherto not achieved. The spacer group is shown to provide the twin benefits of enhanced reactivity and solubility in water. The high pK(a) at > or =9.90 of these copolymers estimated from potentiometric studies demonstrates packing of AMPS segments as ionic clusters. The higher CAB in copolymer C provides the most densely packed nonpolar microdomains. From fluorescence quenching studies, the cross-linking provided by the cholesterol chains favoring intra- or intermolecular aggregated structures has been established. At the air/solution interface, copolymer C exhibits the most close-packed structures exhibiting "a" of 41.2 A(2)/molecule. The effect of neutralization on the adsorption characteristics is investigated.

Abstract
The response of unentangled polymer thin films to aqueous hydroxide solutions is measured as a function of increasing weakly acidic methacrylic acid comonomer content produced by an in situ reaction-diffusion process. Quartz crystal microbalance with energy dissipation and Fourier transform infrared spectroscopy measurements are used to identify four regimes: (I) nonswelling, (II) quasiequilibrium swelling, (III) swelling coupled with partial film dissolution, and (IV) film dissolution. These regimes result from chemical heterogeneity in local composition of the polymer film. The acid-catalyzed deprotection of a hydrophobic group to the methacrylic acid tends to increase the hydrophilic domain size within the film. This nanoscale structure swells in aqueous base by ionization of the methacrylic acid groups. The swollen film stability, however, is determined by the hydrophobic matrix that can act as physical cross-links to prevent dissolution of the polyelectrolyte chains. These observations challenge current models of photoresist film dissolution that do not include the effects of swelling and partial film dissolution on image quality.

Abstract
Mixing of aqueous solutions of poly(acrylic acid) and (hydroxypropyl)cellulose results in formation of hydrogen-bonded interpolymer complexes, which precipitate and do not allow preparation of homogeneous polymeric films by casting. In the present work the effect of pH on the complexation between poly(acrylic acid) and (hydroxypropyl)cellulose in solutions and miscibility of these polymers in solid state has been studied. The pH-induced complexation-miscibility-immiscibility transitions in the polymer mixtures have been observed. The optimal conditions for preparation of homogeneous polymeric films based on blends of these polymers have been found, and the possibility of radiation cross-linking of these materials has been demonstrated. Although the gamma-radiation treatment of solid polymeric blends was found to be inefficient, successful cross-linking was achieved by addition of N,N'-methylenebis(acrylamide). The mucoadhesive potential of both soluble and cross-linked films toward porcine buccal mucosa is evaluated. Soluble films adhered to mucosal tissues undergo dissolution within 30-110 min depending on the polymer ratio in the blend. Cross-linked films are retained on the mucosal surface for 10-40 min and then detach.

Abstract
Hydrophobically associating copolymers of acrylamide (AM) with a small amount of 4-(omega-propenoyloxyethoxy) benzoic acid (PEBA, <2.5%) were synthesized by template copolymerization in the presence of poly(allylammonium chloride) (PAAC) as a template in an aqueous medium. These template copolymers exhibited remarkable thickening properties due to the effective hydrophobic association, which were similar to those copolymers with a multiblock structure obtained by the micellar process. The pH of the reaction medium and the molecular weight of the template strongly influenced the thickening properties of the products. In the experimental range, the higher the PEBA content, the larger the thickening capacity of these hydrophobic copolymers. The aggregate behaviors of these copolymers were studied by fluorescence, transmission electron microscopy (TEM), and light scattering techniques. The apparent critical interpolymer aggregate concentration (cac) of the copolymer solution was about 0.5 g/dL. As the concentration of the copolymer became higher than the cac, the aggregates changed their morphology from small hollow spheres to big flower-shaped aggregates. All the above results indicated that the template copolymerization gave access to a very simple and powerful means for the preparation of hydrophobically associating copolymers and other functional polymer materials.
