POE toughened PP stiffness-toughness balance poor

Stiffness-toughness balance requires ternary system and optimized POE particle size

POE/PP dynamic crosslinking crosslinking degree insufficient

TPV crosslinking degree insufficient; optimize DCP/TAIC and shear

POE toughened PP low-temperature impact insufficient

Low-temperature toughening requires lower Tg and stronger interfacial adhesion

POE toughened PP impact strength not up to standard

The key to POE toughened PP is dispersed phase 0.2-0.5μm and interfacial adhesion
