摘　　要：采用乳液聚合法制备丙烯腈-丁二烯-(α-甲基苯乙烯)接枝共聚物(ABMS)和α-甲基苯乙烯-丙烯腈共聚物(α-MSAN),再将ABMS与α-MSAN熔融共混制备了ABMS树脂,并研究了其力学性能、热性能与形态结构。结果表明:ABMS树脂的韧性随着橡胶相含量的增加而逐渐增大,拉伸强度先增加后减少;引入α-甲基苯乙烯可以改善丙烯腈-丁二烯-苯乙烯树脂的稳定性;橡胶相含量的增加能使ABMS树脂的耐热性能提高;橡胶相含量较高的ABMS树脂从深层次发生断裂,其抗冲击性能较好。Acrylonitrile(AN)-butadiene(Bd)-(α-methyl styrene)(ABMS)grafted copolymer andα-methyl styrene-acrylonitrile(α-MSAN)copolymer were synthesized by emulsion polymerization,which wereused to prepare ABMS resin via melt blending.The mechanical and thermal properties as well as morphologyof ABMS resin were investigated.The results show that the toughness of the resin follows the increase of rubberphase content while its tensile strength first increases and then decreases.The introduction ofα-MS enhances thestability of AN-Bd-styrene(ABS)resin.The improvement of heat resistance of ABMS resin was achieved withincreasing of rubber phase content.The ABMS resin in high rubber phase content ruptures from deep section,representing excellent impact properties.
