Abstract

In this paper, -isotactic polypropylene ( -iPP) samples were prepared by adding two nucleating agents with different particle sizes (NT-C and ST-C). The melting, crystallization and mechanical properties of -iPP samples were investigated by means of differential scanning calorimetry (DSC) and mechanical tests. It is revealed that the nucleation efficiency and crystallizaton ability of iPP/ST-C (fine size and narrow distribution) is better than those of iPP/NT-C (coarse size and wide distribution). It is also found that tensile strain at break and notched impact strength increase for the -nucleated iPP specimens. The superior toughness is obtained for iPP/ST-C specimens.
