摘要: 合成了乙烯-辛烯共聚物(POE)和甲基丙烯酸甲醋(MMA)-丙烯腈(SAN)-苯乙烯(St)的接枝共聚物(POE-g-MAS)。研究了单体比率、POE/单体比率和引发剂浓度等因素对接枝共聚合反应的影响。聚合产物用丙酮抽提得到接枝共聚物POE-g-MAS,傅里叶变换红外光谱分析证明MMA-AN-St已经接枝在POE分子链上。用POE-g-MAS与Stet树脂共混制备了具有高抗冲性能的POE-g-SAN/SAN共混物,并用扫描电镜观察共混物的冲击断面,探讨了其增韧机理。

Abstract: Polyethylene-octene elastomer(POE)-graft- methyl methacrylate/acrylonitile/styrene (POE-g-MAS) was synthesized by grafting methyl methacrylate(MMA),acrylonitrile(AN) and styrene (St) onto POE elastomer. }Che effect of weight ratios of POE to the three monomers and initiator concentration on the graft copolymerization were investigated. the graft copolymer was extracted with acetone from the system and was characterized using F}L}IR spectroscopy. It showed that MMA-An-St was grafted onto the POE chains. Introducing the POE-g-MAS into SAN resin by melt blending generated a novel high impact engineering plastics, POE-g-MAS/SAN.SEM analysis showed that POE-g-MAS had good compatibility with SAN resin.

Key words: polyethylene-octene elastomer, suspension grafting copolymerization, tougheness
