Abstract
One-pot free-radical polymerization of N-acryloyl glycinamide in the presence of hyaluronic acid as transfer-termination agent led to new copolymers in high yields without any chemical activation of hyaluronic acid before. All the copolymers formed thermoresponsive hydrogels of the Upper Critical Solution Temperature-type in aqueous media. Gel properties and the temperature of the reversible gel ↔ sol transition depended on feed composition and copolymer concentration. Comparison with mixtures of hyaluronic acid-poly(N-acryloyl glycinamide) failed in showing the expected formation of graft copolymers conclusively because poly(N-acryloyl glycinamide) homopolymers are also thermoresponsive. Grafting and formation of comb-like copolymers were proved after degradation of inter-graft hyaluronic acid segments by hyaluronidase. Enzymatic degradation yielded poly(N-acryloyl glycinamide) with sugar residues end groups as shown by NMR. In agreement with the radical transfer mechanism, the molar mass of these released poly(N-acryloyl glycinamide) grafts depended on the feed composition. The higher the proportion of hyaluronic acid in the feed, the lower the molar mass of poly(N-acryloyl glycinamide) grafts was. Whether molar mass can be made low enough to allow kidney filtration remains to be proved in vivo. Last but not least, Prednisolone was used as model drug to show the ability of the new enzymatically degradable hydrogels to sustain progressive delivery for rather long periods of time in vitro.

Abstract
The interactions between model polyanions and polycations have been studied using frontal continuous capillary electrophoresis (FACCE) which allows the determination of binding stoichiometry and binding constant of the formed polyelectrolyte complex (PEC). In this work, the effect of the poly(l-lysine) (PLL) molar mass on the interaction with statistical copolymers of acrylamide and 2-acrylamido-2-methyl-1-propanesulfonate (PAMAMPS) has been systematically investigated for different PAMAMPS chemical charge densities (15% and 100%) and different ionic strengths. The study of the ionic strength dependence of the binding constant allowed the determination of the total number of released counter-ions during the formation of the PEC, which can be compared to the total number of counter-ions initially condensed on the individual polyelectrolyte partners before the association. Interestingly, this fraction of released counter-ions, which was strongly dependent on the PLL molar mass, was almost independent of the PAMAMPS charge density. These findings are useful to predict the binding constant according to the molar mass and charge density of the polyelectrolyte partners.

Abstract
In this study, a novel water-insoluble polyelectrolyte complex between chitosan and poly(acrylic acid- co-maleic acid) was prepared and characterized. The chitosan used (M̅v = 23,000–60,000 g/mol) formed water-insoluble polyelectrolyte complexes at pH 2.2–4.8 and water-soluble chitosan oligomers (M̅v = 2,700 g/mol) at pH 2.2–7.4. The polyelectrolyte complexes formed were used in the preparation of novel carriers for a Trichoderma spp. biocontrol agent. Three types of beads were prepared: noncross-linked chitosan beads, coated with a chitosan/poly(acrylic acid- co-maleic acid) polyelectrolyte complex; genipin-cross-linked chitosan beads; and cross-linked chitosan beads, coated with a chitosan/poly(acrylic acid- co-maleic acid) polyelectrolyte complex. Trichoderma viride was immobilized either in the bulk or in the surface layer of the beads. The microbiological tests confirmed that T. viride immobilized in either mode maintained viability and the capacity to develop and to inhibit the growth of the pathogenic soil microorganisms, Alternaria and Fusarium.

Abstract
To improve the understanding of the physicochemical behavior of polyplexes (DNA-polycation complexes) and to avoid the complexity of blood, the formation and stability of polyelectrolyte complexes of degradable polycations and polyanions, we previously studied under pH, temperature, and ionic strength typical of human blood. In this study, the investigation is extended to polycationic macromolecules added into mixtures of polyanions selected to mimic polyanionic species present in blood. The poly(l-lysine) polycation was added to binary mixtures of degradable polyanions with different charge densities and hydrophobicity. The polyanions were poly(l-lysine citramide imide), poly(l-lysine citramide), and poly(l-lysine citramide) partially esterified with heptyl groups. We found selectivity and fractionation in the molar mass, which depended on the structural characteristics of the polyanions. The affinity of polycationic poly(l-lysine) macromolecules to polyanions increased in the following order: poly(l-lysine citramide imide) < poly(l-lysine citramide) < hydrophobized poly(l-lysine citramide). These data complements the previous information with respect to the possibility of polyplex destabilization and/or the interactions of polycationic macromolecules in excess with the polyanionic species present in blood, depending on the physicochemical characteristics of the polyplex, the excess polycation, and blood elements.

Abstract
To understand the fate of anionic macromolecular species when injected into blood, poly(acrylic acid) and poly(L-lysine citramide) polyanions, with better charge densities, and the poly(L-lysine) polycation were used as models of negatively charged polymer—drug conjugates and positively charged blood proteins, respectively. To mimic an intravenous injection, the polyanion was added to the poly(L-lysine) stepwise at room temperature. The polyelectrolyte complexes formed as precipitates and the molar mass fractionation was observed from one fraction to the other, especially in the case of largely polydispersed poly(L-lysine). The salt concentration necessary to return each fraction of complexed polyelectrolyte back to solution varied linearly with the logarithm of the molar mass of the polycation component. The physicochemical characteristics data of the polyelectrolytes and the media are compared to previously reported reverse mixing mode when the polycation is introduced into a solution of polyanions.
