摘　　要：采用过氧化物降解法在气相Spherizone工艺聚丙烯装置上,添加过氧化物降解剂生产纤维专用乙丙无规共聚聚丙烯PP-1,并选取典型同类进口产品进行对比分析。结果表明:与进口产品A相比,PP-1具有熔体流动速率高、相对分子质量分布窄等特点,赋予纤维较高的取向度及纺丝连续性,纤维应变硬化快,不易断丝。Ethylene-propylene random copolymerized polypropylene(PP)fiber specialty,PP-1,was produced via peroxide degradation in gas phase Spherizone unit,which was compared with the typical similar imported product.The results show that the higher melt flow rate and narrower molecular mass distribution of PP-1 contribute to the fiber's higher orientation,continuous spinning,fast strain hardening,and difficulty to break the yarn.
