The synthesis of novel water-soluble cationic amino esters based on cellulose and dextran under homogeneous conditions is presented in this work. Products are synthesized via the ring-opening reaction of N-methyl-2-pyrrolidone in the presence of p-toluenesulfonyl chloride: cellulose-4- N-methylammonium]butyrate chloride, hydroxyethyl cellulose-4- N-methylammonium]butyrate chloride and dextran-4- N-methylammonium]butyrate chloride. Cellulose-4- N, N, N-trimethylammonium]butyrate chloride is obtained by conversion of cellulose with (3-carboxypropyl)trimethyl ammonium chloride activated with N,...
