摘要

本文采用溶液法以单酚（４－氯－４’－羟基二苯砜）为原料合成了不同聚合度的单酚低聚体，得到了控制聚合度的最佳聚合条件；用相转移催化剂法成功地将单酚转化为单烯大分子单体，并用ＩＲ、１Ｈ—ＮＭＲ对其结构进行了表征；测定了双键官能度均在１．９０以上．单烯大分子单体与苯乙烯的共聚研究表明，聚合度为２左右的单烯大单体在苯乙烯中溶解度最大，可达８０％以上；共聚物有优异的光学特性，对折射率的提高比相应的双烯大分子单体有利；在可见及近红外区透光率达８９％以上．

Abstract

n thes paper

the oligomers with different molecular weight of monohydroxylpolyethersulfones were synthesized in solution and the optimum condition ofpolymerization was obtained; With phase transfer catalyst method

the oligomerswas obtained and transformed to monovinylpolyethersulfones macromer. Its structure was characterized with IR and 1H-NMR.The copolymerization ofmonovinyl-macromer and styrene was studied.The monovinyl-macromer whosedegree of polymerization is 2 has the highest solubility in styrene(S>80% by weight); The copolymer is superior to the copolymer of divinyl-macromer in raising the refractive index of optical plastics. Its transmittance in vis-nir region is about 89%.
