摘要

Abstract

A propylene-based elastomer (PBE) and calcium phthalate (CaPh) were selected to modify polypropylene (PP)

via

melt blending. The prepared PP blends exhibited excellent impact toughness and crystalline properties owing to the synergistic effects of PBE and CaPh. The dispersed PBE phase in the PP matrix acted as numerous stress concentrators

initiated shear banding

and impeded the crack propagation. The impact strength of the PP/PBE blends progressively increased with increasing PBE content. CaPh functioned as a

-nucleating agent and effectively induced the formation of a high content of

-crystals in PP. The DSC resu

lts indicated that CaPh exhibited high nucleation efficiency

acting as a heterogeneous nucleating agent to improve the crystallization of PP and PBE. With the incorporation of 15 wt% PBE and 0.05 wt% CaPh

the content of

-crystals reached 87.1% and the impact strength of PP enhanced to 50.9 kJ/m
