二苄叉山梨醇(DBS)是等规聚丙烯的成核剂。本文应用小角激光散射法研究散射强度与DBS含量的关系,并进行了计算。应用光散射模型理论和统计理论探讨聚丙烯加入DBS后形态结构的变化。
Dibenzylidene sorbitol (DBS) is a nucleating agent for isotactic polypropylene. In this paper, the application of small-angle laser light scattering method to study the relationship between the scattering intensity and DBS content, and calculated. The light scattering model theory and statistical theory were used to investigate the morphological changes of polypropylene after adding DBS.
