采用PB-g-SAN和SBR-g-SAN两种弹性体粒子分别与SAN树脂熔融共混，制得了一系列ABS树脂，研究了ABS树脂的形态结构和力学性能。结果发现，PB和SBR橡胶粒子均匀地分散在SAN基体中，其粒径分别为0.28μm和0.05μm左右。力学性能结果表明，在SAN树脂中随着PB-g-SAN含量的增加，ABS的冲击强度不断提高，而SBR小橡胶粒子不能增韧SAN树脂。但当SAN树脂中含有15%的PB-g-SAN共聚物时，随着SBR-g-SAN含量的增加，ABS树脂的冲击强度不断提高，SBR-g-SAN这种小橡胶粒子又表现出良好的增韧作用。

A series of ABS resins were prepared by melt blending PB-g-SAN and SBR-g-SAN elastomers with SAN resins respectively.The morphology and mechanical properties of ABS resins were studied.It was found that PB and SBR rubber particles were dispersed homogeneously in SAN matrix，and their particle sizes were about 0.28μm and 0.05μm respectively.The determination of mechanical properties showed that the impact strength of ABS resins increased gradually with increasing PB-g-SAN content in SAN matrix，and SAN resins could not be effectively toughened by SBR rubber particles.When PB-g-SAN content was 15％ in ABS resins，the impact toughness of ABS resins was improved gradually with increasing SBR-g-SAN content in SAN resins.
