高流动性高韧性PP共混体系的研究

本文采用三元乙丙胶（ＥＰＤＭ）和增韧母料对ＰＰ进行共混增废 性，同时采用降温母料的流动性，还探讨了ＬＤＰＥ、ＬＬＤＰＥ、ＨＤＰＥ和马来酸酐接枝物等对体系性能的影响。运用扫描电（ＳＥＭ）和偏光显微镜对共混物的微观结构和结晶状况进行了观察与分析，探讨了微观结构、结晶情况与共混物力学性能以及流动性间的关系。

The Study of High Fluidity and Toughness PP Blends

In this paper,PP is modified by blending and toughening with EPDM and toughening master batch.Degradable master batch is used to improve fluidity of the compounds.The influence of LDPE,LLDPE,HDPE and MAH g PP on blends are also investigated.The micro structure and crystallinity of blends are observed and analyzed with SEM and polarizing microscope respectively.The relationships among micro structure,crystallinity and the mechanical properties and fluidity of blends are investigated.;
