The Study on the Polymeric Bactericidal Flocculants Ⅲ. The Polymerization Mechanism of Poly(dially ammonium halide-sulfon) and its Structure

本文合成了二烯丙基甲基十二烷基季铵盐与二氧化硫的交替共聚物。研究了该聚合体系的聚合机理,由共聚组成与反应速率的关系分析了络合物与自由单体参与增长的不同体系。通过^(13)C-NMR分析确定了共聚物具有五员环状结构。

The copolymerization of Methyldodecyldiallyl ammonium halide with SO_2 hasbeen studied. The ratio of diallyl compounds to SO_2 in copolymers prepared by freeradical polymerization has been found to be 1:1, which together with the relationshipbetween the composition and conversion of copolymers led to the suggestion ofcopolymerization mechanism. The copolymerization was carried out in terms of com-plex propagation reaction of 1:1 diallyl compound/SO_2 molecular complex and freemonomers varied with the systems. The copolymers prepared were proved to have the structure as followedby ^(T3)C--NMR spectroscopy.
