The interaction of polyethylene glycol ester with chitosan was also confirmed by conductometric titration and stoichiometry ratio (COOH\/NH<\/em><em>2<\/em><em>) determined by this method being approximately equal to 1. It was found that the electric field increased micro-heterogeneity\u2019s level of samples, but almost no effect observed on the amorphous and amorphous-crystalline structure.
