摘要

研究了氮杂环鎓盐协同γ射线引发氧化环己烯阳离子开环聚合反应。在研究阳离子聚合阻聚剂、不同气氛条件及聚氧化环己烯分子量和分布后，认为在反应体系中鎓盐氧化射线产生的自由基成为阳离子，并向体系贡献弱亲核性阴离子而引发氧化环己烯阳离子开环聚合。讨论了不同极性溶剂对该聚合反应的影响，同时初步研究了引发此聚合反应活性中心。

Abstract

A study was carried out on radiation-induced cationic polymerization enhanced by the N-Alkoxypyridinium salt having relatively stable nonnucleophilic anion (PF,6,). After investigations on the cationic inhibitors, different atmosphere conditions and the molecular weight and its distribution, it was proved that the cationic polymerization to take place in CHO/ CH,2,Ｃl,2, or C,6,H,6,/ EMP,+,PF,6, system on irradiation with theγ-rays. The onium not only oxidated α-alkoxyalkyl radicals, produced from CHO in dichloromethane, to the correspondings cations, but also gave nonnucleophilic anions PF,6, for the polymerization system. A preliminary discussion is made on the effect of different polar solvents to reactive centers.
