| 摘 要： | 采用种子乳液聚合方法，合成一系列苯乙烯-丙烯腈共聚物接枝聚丙烯酸丁酯（PBA-g-SAN）核壳接枝共聚物，将其与苯乙烯-丙烯腈共聚物（SAN树脂）熔融共混，制得ASA树脂，使用动态力学分析仪和扫描电子显微镜考察了扩径中接枝剂的含量和PBA橡胶粒径对ASA树脂性能的影响。结果表明，随着接枝剂含量的增加，PBA-g-SAN接枝共聚物的接枝率升高，当接枝剂占单体BA的3%时，ASA树脂的冲击强度达到110 J/m。ASA树脂的冲击强度随着橡胶粒径的增加先升高后降低。PBA-g-SAN接枝共聚物中PBA的玻璃化转变温度(（Tg）随着接枝剂含量的增加而升高，随着PBA橡胶粒径的增加先降低后升高。当PBA橡胶粒径为92.7 nm时，橡胶粒子发生聚集，其他粒径的PBA橡胶均可较好地分散在基体中。

| Abstract: | PBA latex was synthesized by emulsion polymerization,onto which acrylonitrile and styrene monomers were grafted.The grafted product was melt blended with SAN copolymer forming an ASA resin.The effect of grafting monomers and PBA latex size on the structure and property of ASA resin was studied.It showed that the grafting degree was increased with increasing loading of grafting monomers,and the impact strength of ASA resin increased and then decreased with an increasing grafting monomers and PBA latex partic... |
