摘    要:以高密度聚乙烯(HDPE)为基体,采用气-固氯化原位接枝反应合成了以氯化聚乙烯(CPE)为骨架聚合物、丙烯酸-2羟基乙酯(HEA)为支链的接枝共聚物.反应中不需要加入任何引发剂,以氯自由基引发接枝及氯代反应,得到羟基官能化CPE接枝聚合物.并用1H-NMR,FT-IR,GPC及X-射线衍射等对接枝共聚物的结构进行了表征.

关 键 词:官能化  CPE-g-HEA  氯化原位接枝  结构表征

Abstract:A grafting copolymer(CPE-g-HEA),composed of poly(2-hydroxy ethyl acrylate)(PHEA)as branched chains and chlorinated polyethylene(CPE)as backbone,was synthesized by in situ chlorinating graft copolymerization.No any initiator was added in the system.The process of in situ chlorinating graft copolymerization comes from continuously introducing chlorine gas into the reaction mixtures composed of only high-density polyethylene powder and a little amount of 2-hydroxy ethyl acrylate(HEA).When heated,a chlorine molecule decomposed into two chlorine radicals,which can lead to chlorination of PE,grafting of HEA to PE and homopolymerization of HEA as well.The structure of CPE-g-HEA was characterized by FT-IR,1H-NMR,GPC and WAXD.The results of FT-IR,1H-NMR and GPC indicated the existence of grafting copolymer of CPE-g-HEA.It can be found that the side chains of the copolymer were very short compared with those of HEA by bulk polymerization according to the GPC trace,and also the copolymer had more branches compared with the aqueous suspension graft system(CPE-g-MMA).
Keywords:Functionalization  CPE-g-HEA  in situ chlorinating graft copolymerization  Structure characterization
