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%.
