摘要
本文采用偏光显微镜、X射线衍射和扫描电子显微镜,对含β成核剂的IPP/LDPE共混体系进行研究,首次阐明了熔融温度、冷却速率对共混体系中β-IPP晶体形成及结构的影响,以及β-IPP与LDPE的共混规律和组分含量对β-IPP晶体结构的影响。
The IPP/LDPE blends prepared with P-form crystall nucleating agents, had been studied by PLM, X-ray diffraction and SEM. The influence of melting temperature, cooling rate, and the content of LDPE on the formation and structure of P-form crystalls of IPP in the blends, as well as the mixing property between P-IPP and LDPE, had been described for the first time.
