摘要：

The effect of a new liquid crystalline copolymer( LCP-H2 ) on the crystallization structure of isotactic polypropylene( iPP ) was investigated using wide-angle X-ray diffraction. The experimental results show that LCP-H2 of low mass fraction can induce beta-form in iPP. The nucleating activity of LCP-H2 mainly depended on its content and crystallization temperature. The content of beta-form ( K-beta ) increased with increasing the nucleator content and crystallization temperature, K. value reached a maxi mum value ( 35% ) when the nucleator mass fraction was 0. 8% and the crystallization temperature was 125 degrees C.
