Graft Polymerization of 5-Vinyltetrazole onto Chitosan
Polymerization of 5-vinyltetrazole under conditions of radical initiation in aqueous media in the presence of chitosan gave network graft copolymers, the structure of which is built from chitosan macromolecules crosslinked by chain fragments of poly(5-vinyltetrazole). It was determined that the polymerization is preceded by the formation of a saltlike product between chitosan macromolecules and vinyl monomer, which affects its polymerization activity. The obtained graft copolymers are prone to limited swelling in water to form pH-sensitive ampholytic hydrogels.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
