摘　　要：过氧化二异丙苯（DCP）能有效降解PP；当DCP用量为2‰（质量分数）时，PP／EPDM共混物的冲击强度较高。共混物的相形态结构表明，EPDM橡胶粒子均匀地分散在基体中。The dicumyl peroxide （DCP） could effectively degrade the PP. The impact strength of PP/EPDM was higher when the content of DCP was 2wt‰. The phase morphology of blend indicated that the EPDM particles dispersed into the matrix evenly; the interracial adhesion between the EPDM phase and the PP phase was strengthened by the dynamic crosslinking.
