摘要
提供了一种在低熔体流动速率聚丙烯中加入分子量降解剂和稳定剂，并通过双螺杆挤出工艺制备纤维级聚丙烯的方法，考察了分子量降解剂及各种稳定剂对产品性能的影响，成功地开发了纤维级聚丙烯。
A method of fiber-grade PP produced by adding polymer degradation agent and antioxidative stabilizer in low MFR PP during the blend-extrusion process was provided. The effects of polymer degradation agent and stabilizing agents on the product properties were investigated. The development of fiber-grade PP had success.
