摘　　要：采用红外光谱法对EPDM-g-MMA进行表征,利用SEM、WAXD等手段及力学性能测试设备研究了EPDM-g-MMA对POM/EPDM共混物的增容作用。结果表明,相容剂EPDM-g-MMA加入,使POM/EPDM共混物的分散相颗粒细化,结晶度X_c降低,拉伸强度、缺口冲击强度、断裂伸长率均增大,说明了EPDM-g-MMA的增容作用。EPDM-g-MMA was characterized with IR spcctrograph, and compatibilization of EPDM-g-MMA for POM/EPDM blend was investigated with mechanical property test instrument, SEM, WAXD etc. The results showed that the particle of dispersed phase of POM/EPDM blend got fine, the crystallinity Xc. decreased, and the tensile strength, notch impact strength and breaking elongation increased with adding compatibilizer EPDM -g -MMA. It was proved that EPDM-g -MMA had compatibilization for POM/EPDM blend.
