摘　　要：按ASTM标准测定了两种用于汽车保险杠和仪表板的PP/EPDM共混材料的物理力学性能和热变形温度、MI等,用TME、SEM和MPA研究了这种PP/EPDM共混体系的形态结构,通过偏光显微镜研究了EPDM对PP球晶的影响,用DSC对这种PP材料进行了热分析。The mechanical properties, heat deflection temperature and MI of PP/EPDM for making bumper and dashboard were de-termined according to ASTM standard. The morphology of the PP/EPDM was studied by TEM, SEM and MPA. By means ofpolarizing microscope, the influence of EPDM on the PP spherulite was observde. DSC technique was also employed to the ther-mal analysis of these materials.
