聚苯乙烯接枝聚氧乙烯两亲接枝共聚物合成的研究

STUDY ON THE SYNTHESIS OF POLYSTYRENE GRAFT POLY (ETHYLENE OXIDE)AMPHIPATHIC GRAFT COPOLYMER

本文采用大分子单体法合成了结构明确的两亲接枝共聚物—聚苯乙烯接枝聚氧乙烯 ( PS— g—PEO) ,通过 IR,NMR和 GPC系统表征了两亲接枝共聚物。通过定性和定量的表征研究 ,结果证明两亲接枝共聚物 PS— g—

Amphipathic graft Copolymer,Polystyrene-graft-poly(ethylene oxide),was synthesized by the radical solution copolymerization of the macromonomer PEO with comonomer (styrene). The copolymer expected structure was obtained by controlling the reaction condition and content of AIBN, PEO, St etc.and could be effectively adjusted. The copolymers exhibited the expected structure as indicated by the results of detailed charcterization with FT-IR, 1H-NMR, GPC, etc,.
