【Abstract】 Modification effect of polyolefin elastomer (POE) on polypropylene (PP) was compared with that of ethylene/propylene/diene mischpolymer (EPDM) on PP. Different influences of POE and EPDM on PP blended with toughening masterbatch and temperature controlled masterbatch were discussed. Microstructure and crystallinity of the blends were analyzed by SEM and DSC respectively.更多还原
