| 摘 要： | 合成了乙烯-辛烯共聚物(POE)和甲基丙烯酸甲酯-丙烯腈-苯乙烯的接枝共聚物(POE-g-MAS).用POE-g-MAS与苯乙烯-丙烯腈共聚物(SAN)树脂共混制备了具有高抗冲击性能的SAN,POE-g-MAS共混物,研究了接枝链极性、接枝率和POE含量对共混物冲击性能的影响,当m(St)/m(MMA)/m(An)为10:70:20,接枝率为45.1%,w(POE)为25%时,共混物的缺口冲击强度达到56.1kJ/m2.用扫描电子显微镜和差示扫描量热仪研究表明,POE-g-MAS与SAN树脂有良好的相容性.

| Abstract: | The authors synthesized a graft copolymer (POE-g-MAS) by grafting methyl methacrylate-acrylonitrile- styrene (MAS) onto polyethylene-octene elastomer (POE). Furthermore,POE-g-MAS was blended with styrene- acrylonitrile resin to prepare a novel high impact engineering plastic (SAN/POE-g-MAS). The effects of polarity of graft chain,grating ratio and POE content on impact property of the blending were studied. The notch impact strength of the blending reached 56.1 kJ/m~2 when m(St)/m(MMA)/m(An) ratio,graft rat... |
