采用化学控制降解法调节聚丙烯的分子量和分子量分布,以控制纺丝线上的结晶,可明显降低聚丙烯纺丝温度,提高成丝质量和生产效率,产生显著的经济效益。作者曾提出用聚内烯流动性能估算它的分子量及分子量分
The chemical control of degradation of polypropylene molecular weight and molecular weight distribution regulation to control the spinning line crystallization can significantly reduce the polypropylene spinning temperature and improve the quality of silk and production efficiency, resulting in significant economic benefits. The authors have proposed to estimate the molecular weight and the molecular weight fraction of the polyene by using its mobility
