对甲氧基苯乙烯在离子液体中的正离子聚合
The Cationic Polymerization of p-Methoxystyrene in Ionic Liquid
摘要
Abstract
Cationic polymerization of p-Methoxystyrene (p-MOS)was achieved in imidazole phosphate ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim ][PF6 ]) with 2-chloro-2,4,4-trimethyl pentane (TMPCl ) and boron trifluoride (BF3 )as a initiating system at -10 ℃.The polymer molecular weight achieved 73 150 g/mol,and monomer conversion was more than 93.4%.The influence of reaction temperature and monomer concentrationon the polymerization was analyzed,and the molecular structure was characterized by 1 H-NMR.The results showed that there were two different ends structure of polymer,including chlorine end groups and double bond end groups,and the corresponding mechanism of cationic polymerization of p-Methoxystyrene in ionic liquid was proposed.关键词
