KARBOKSIMETILKRAXMAL ASOSIDAGI BIOPARCHALANUVCHI POLIMER PLYONKALAR
In this research, sodium salt (Na-CMS) of carboxymethyl starch was obtained by chemical modification of corn starch in the solid phase. The influence of various factors on the degree of substitution of the resulting Na-CMS was studied. Na-CMS macromolecules were cross-linked with ions of multivalent metals, and film materials were obtained on the basis of the resulting polymer hydrogels. The influence of the nature and amount of metal ions used for cross-linking the polymer on the transparency and elasticity of the resulting polymer films was shown.
