摘　　要：聚丙烯(PP)低劣的冲击和低温性能影响了这类通用塑料的工程化和功能化。本工作用聚乙二醇(PEG)包覆硅灰石,有效地提高了填充PP的缺口冲击强度和低温性能。同时讨论了PEG用量和分子量对填充PP的性能和断面形貌、PP的结晶形态的影响。The wollastonite encapsulated by polyethylene glycol (PEG) have been used to increase the notched-impact strength and to improve the low-temperature properties of polypropylene (PP). The influence of the amount and the molecular weight of PEG on the properties of filled PP has been investigated. And, the sectional morphology and crystalline state of PP Composite has been disscued.
