众所周知,聚合物的机械性能和加工性能很大浪度上与高聚物分子量及其分布有关。化纤工业所用原料聚合物的聚合度分布对纤维的制造过程和成品纤维的机械强度具有特殊意义。 维尼纶生产中的PVAc(聚醋酸乙烯酯)与PVA(聚乙烯醇)的聚合度分布问题早为人
It is well known that the mechanical properties and processing properties of polymers are closely related to the molecular weight of the polymer and its distribution. The polymerization degree distribution of the raw material polymer used in the chemical fiber industry is of special significance to the manufacturing process of the fiber and the mechanical strength of the finished fiber. Vinylon production in the PVAc (polyvinyl acetate) and PVA (polyvinyl alcohol) degree of polymerization as early as the distribution of people
