摘要
研究了聚丙烯化学降解过程中降解剂对聚丙烯熔体流动速率和分子量分布的影响。试验结果表明,降解后聚丙烯具有较高的熔体流动速率和较窄的分子量分布,能满足纤维级专用料的性能要求。
Effects of the degradative agents on the melt flow rate and molecular weight distribution of polypropylene during chemical degradation were investigated The results showed that the degraded polypropylene has higher melt flow rate and narrower molecular weight distribution, it could meet the need of fiber-grade polypropylene special resins
