Elastoviscous Systems Based on Solutions of Chitosan–Methyl Acrylate and Chitosan Succinamide–Methyl Acrylate Copolymers

Resumo

Rheological studies of solutions of amphiphilic copolymers based on hydrophilic polysaccharides chitosan (CT) and chitosan succinamide (CTS) sodium salt with methyl acrylate (MA) synthesized by radical copolymerization have been conducted. It has been found that the hydrophobic interaction of poly(methyl acrylate) blocks in solutions of CT–MA and CTS–MA copolymers leads to an increase in the degree of structuring of macromolecules; this feature leads to the formation of an elastoviscous system without introducing of an additional crosslinking agent.
