聚氯乙烯树脂的形态与聚合方法

Relationship between the Morphology of the Polyvinyl Chloride Resin and Its Polymerization Method

用透射式电镜和X-射线衍射分析对国内外三种聚合方式合成的聚氯乙烯树脂进行了表面形态的比较观察和聚集态结构的研究,测量了树脂粒子的平均粒径,分散系数以及树脂的有序结构.结果表明聚合方法对树脂形态、粒径、分散系数和聚集态结构均有一定程度的影响.

The apparent morphology,the state of aggregation and the particle diameters of polyvinyl chloride resins by different polymerizations are investigated by transmiting electron microscopy and X-ray diffraction patterns. Their average diameter and the dispersion coefficient are measured. The results show that the morphology, the state of aggregation and the particle diameters of the resin are Connected closely with the method of polymerization.
