β-晶型成核剂在聚丙烯增韧体系中的应用

Application of β-crystalline Form Nucleation Agents in PP Toughening Sytems

研究了 β -晶型成核剂在PP/PET、PP/BR、PP/LLDPE三种共混物中的应用效果。结果表明 ,再增韧聚丙烯中应用β -晶型成核剂 ,可以减少增韧剂用量 ,提高抗冲击性能 ,改善加工性能。

S\;The effects of β-crystalline form nucleation agent applied in PP/PET, PP/BR and PP/LLDPE blends have been studied respectively. The results show that contents of toughening agents can be reduced,and impact strength and process ability of PP can be improved as β-crystalline form nucleation agent is used in PP toughening.\;
