摘　　要：通过DSC、SEM和力学性能测试研究了EMA在ABS/PMMA中的作用,结果表明:EMA对ABS/PMMA合金具有增容和增韧作用。因为EMA含有与ABS中丁二烯结构相似的乙烯基,又含有与PMMA中相同的甲基丙烯酸甲酯,可以提高ABS/PMMA的界面相容性,但同时EMA在ABS/PMMA中呈球形分散,起应力集中物作用,能提高ABS/PMMA的韧性;EMA对ABS/PMMA增容程度影响着ABS/PMMA合金的表面光泽度,当EMA质量含量为6%时,ABS/PMMA合金的表面光泽度达到最大值。Effects of EMA on ABS/PMMA blends were studied by DSC,SEM and mechanical performance test. The experimental results showed that the EMA had compatibilizing and toughening effects on ABS/PMMA blends. Because the EMA contains vinyl group similarity to butadiene in ABS, and the same methyl-methacrylate group in PMMA,which could improve the interface compatibility between ABS and PMMA;At the same time, EMA dispersed as spherical in ABS/PMMA matrix and endured stress,the toughness of the ABS/PMMA blends could be obviously improved while increasing the content of EMA. The gloss of the surface of ABS/PMMA blends was affected by the compatibility of ABS/PMMA blends. When the content of EMA was 6 % ,the gloss on surface of ABS/PMMA blends reached maximum.
