分子量分布对合成纤维的纺织性能有直接影响.对尼龙—6来说,平均分子量合适时,分子量分布较窄的树脂在纤维成型中易于纺丝,纤维质量较好;分子量分布较宽的树旨,由于较多的低分子量聚合物的存在,难于纺丝,甚至不能纺丝,纤维质量也差.因此,弄清树脂的分子量分布与聚合工艺条件的关系,以指导聚合;根据分子量分 The molecular weight distribution has a direct impact on the textile properties of synthetic fibers.For nylon-6, the average molecular weight is appropriate, the narrow molecular weight distribution of the resin in the fiber forming process is easy spinning, good fiber quality; broad molecular weight distribution , Due to the presence of more low molecular weight polymers, it is difficult to spin, or even can not be spun, fiber quality is poor.Therefore, clarify the relationship between the molecular weight distribution of the resin and the polymerization process conditions to guide the polymerization; According to the molecular weight
