Abstract
Hydrogels based on sodium alginate (SA) and partially neutralised poly(acrylic acid) were obtained by radical polymerisation. The hydrogels were cross-linked with N,N'-methylenebisacrylamide (MBA), simultaneously grafting the resulting polymer onto SA. The findings of the FTIR spectroscopy showed that all of the hydrogels were effectively synthesized and sodium alginate was chemically bonded with the poly(sodium acrylate) matrix. DSC analysis of the melting heat and glass transition parameters indicated that the hydrogel structure had changed as a result of the cross-linking process. Sodium alginate and MBA were tested at different concentrations to determine how they affected the hydrogel properties. A very high content of the biopolymer, i.e., sodium alginate, was used in our research, up to 33 wt%. This resulted in durable and stable hydrogels with a very high ability to uptake water, comparable to hydrogels based on synthetic polymers only. The ability to swell is inversely proportional to the quantity of MBA present. By increasing the amount of sodium alginate in the hydrogel, the ability of the hydrogel to absorb water is reduced. However, water uptake remains relatively high at 350 g·g-1, even for the hydrogel with the highest SA content.

Abstract
In this paper, the authors discuss the results of research on the preparation and properties of superabsorbent hydrogels based on carboxymethylated high-amylose corn starches. They were obtained by graft copolymerisation (in an aqueous environment) of acrylic acid and its sodium salt onto modified starches (with various substitution degrees DS = 0.2 and 0.8), using potassium persulfate as an initiator and N,N’-methylenebisacrylamide (MBA) as a cross-linker. Modified starches, with various DS, were used to synthesise two series of hydrogels with varying molar ratios of cross-linkers to monomers. The swelling behaviour of hydrogels was studied and their properties were estimated using the kinetic equation. The occurrence of starch–polyacrylic acid covalent interactions was demonstrated by FTIR analysis. Nonlinear rheological methods have proved to be very effective in assessing the mechanical properties of hydrogels. LAOS (large -amplitude oscillatory shear) analysis allowed the determination of the durability of the gel structure as a function of the amount of absorbed water.

Abstract
One high-performance liquid starch-based mulching materials (LSMM) was successfully fabricated by grafting polyacrylic acid (PAA) onto starch then crosslinking with N,N'-methylene-bisacrylamide (MBA). The effects of the dosage of acrylic acid on the performances of LSMM film had been explored. The LSMM was characterized by FTIR, solid state 13C NMR, XRD and SEM. Their application performances by spraying the LSMM on the soil surface also had been discussed. The PAA grafted onto starch significantly improved the properties of LSMM film (tensile strength 20.89 MPa, elongation at break 59.19 %, water absorbency 68.58 g/g and solubility in water 4.5 %). The PAA broke the hydrogen bonds and reduced the crystallinity of starch molecule, which can form the compact structure in LSSM film. As a result, the LSMM showed excellent relative hygroscopicity, water retention, degradability (weight loss 72.61 %) and the effect of facilitating the growth and germination ratio (84.00 %) of lettuce.

Abstract
The substitution of petroleum-based synthetic polymers in latex formulations with sustainable and/or bio-based sources has increasingly been a focus of both academic and industrial research. Emulsion polymerization already provides a more sustainable way to produce polymers for coatings and adhesives, because it is a water-based process. It can be made even more attractive as a green alternative with the addition of starch, a renewable material that has proven to be extremely useful as a filler, stabilizer, property modifier and macromer. This work provides a critical review of attempts to modify and incorporate various types of starch in emulsion polymerizations. This review focusses on the method of initiation, grafting mechanisms, starch feeding strategies and the characterization methods. It provides a needed guide for those looking to modify starch in an emulsion polymerization to achieve a target grafting performance or to incorporate starch in latex formulations for the replacement of synthetic polymers.

Abstract
The aim of the research was to develop new pectin-based hydrogels with excellent swelling properties. Superabsorbent hydrogels composed of high methylated pectin and partially neutralized poly(acrylic acid) was obtained by free radical polymerization in aqueous solution in the presence of crosslinking agent—N,N’-methylenebisacrylamide. The effect of crosslinker content and pectin to acrylic acid ratio on the swelling properties of hydrogels was investigated. In addition, the thermodynamic characteristic of hydrogels was obtained by DSC. Furthermore, the structure of pectin-based hydrogels was characterized by FTIR and GPC. It was also proved that poly(acrylic acid) is grafted on pectin particles. The results showed that introduction of small amount of pectin (up to 6.7 wt %) to poly(acrylic acid) hydrogel increase the swelling capacity, while further increasing of pectin ratio cause decrease of swelling.

Abstract
Abstract
Starch-g-poly(acrylic acid)/organo-mordenite superabsorbent composite microsphere, was prepared by grafting partially neutralized acrylic acid onto starch in the presence of organo-mordenite as an inorganic component. The morphology was characterized with scanning electron microscope (SEM). The swelling properties of the superabsorbent composite microsphere were evaluated in distilled water, various NaCl solutions, solutions with different pH values, and urea solutions. Swelling kinetics of the superabsorbent composite microsphere in above environments were discussed by means of a Schott's second-order model. The results showed that the incorporation of 10 wt% organo-mordenite enhanced the water absorbency by 144% (from 268 to 655 g · g−1) and possessed the maximum swelling absorbency (75 g · g−1) in the 0.9% NaCl solution and (667 g · g−1) in 0.04 mol · l−1 urea solution. Moreover, swelling of starch-g-poly(acrylic acid)/organo-mordenite (with 10 wt% organo-mordenite) in distilled water and in all other environments followed Schott's second order kinetics. Swelling was extremely environmental-responsive to the concentration of the NaCl solution, the pH values, and urea solutions, respectively. The overall results inferred that the novel superabsorbent composite can be exploited for many potential applications.

Abstract
Amylose grafted poly(acrylic acid) (Am-g-PAA) was synthesized by graft copolymerization of amylose with acrylic acid. The structure of Am-g-PAA was confirmed by (1)H NMR and FT-IR spectra. The morphology, crystallinity and thermal properties of amylose and Am-g-PAA were investigated by SEM, XRD and TGA, respectively. The highest degree of substitution (DS) of carboxyl group was 1.96 which was obtained after reacted for 1h at 60°C. Acrylic acid to anhydroglucose mole ratio for DS was 19.81. It was found that a large number of carboxyl groups were grafted on the backbone of amylose. It was also found that ammonia adsorption capacity of amylose increased by grafting poly(acrylic acid) on the backbone of amylose.

Abstract
Lesser usages of native starch has attracted attention in the modification of starch to incorporate its benefits for pharmaceutical application. A work has been carried out to study the influence of carboxymethylation on the morphological, physico-chemical, powder, spectroscopical and drug discharge characteristics of native starch. Various amount of monochloroacetic acid was used to study the influence of degree of substitution (DS) on the diverse characteristics of modified starch. Amylose content was found to be reduced with the increase in degree of substitution. An enhanced degree of structure deformation was observed with the increment in the DS by the help of scanning electron micrographs. The FT-IR spectra established the polysaccharide nature and the carboxymethylation of the chemically modified starch molecules through the new bands at 1602cm-1, and 1418.69cm-1. The stability of carboxymethyl starches pertaining to the temperature has been revealed by thermogravimetric analysis. Micromeritics of carboxymethylated starches shows their effectiveness as excipients in tablet formulation. The delayed % release of the drug, with the rise in degree of substitution from the tablets prepared marks that the carboxymethyl derivatives of Kyllinga nemoralis rhizomes starch may be used as a suitable source of excipient for sustained release formulations.
