摘要

在有壳聚糖存在的水介质中，5-乙烯基四氮唑在自由基引发条件下进行聚合，产生了网络接枝共聚物，其结构是由壳聚糖大分子与聚（5-乙烯基四氮唑）链片段交联而成。经测定，聚合之前壳聚糖大分子和乙烯基单体之间会形成盐状产物，从而影响其聚合活性。得到的接枝共聚物在水中易发生有限的溶胀，形成对 pH 值敏感的两性水凝胶。

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.
