纳米PVC树脂结构性能与流变学特征

The structure properties and rheological characteristics of nano-PVC resin

发明了纳米CaCO3与氯乙烯在工业装置上的原位聚合方法。国内现已有27台30m3以上聚合釜在生产以化学建材为主要市场的纳米PVC树脂。介绍了纳米PVC树脂的颗粒结构特征,并对其热性能、力学和流变性能进行了研究。

A commerical process for the in-situ polymerization of nano-CaCO3 with vinyl chloride is invented.Up to now,27 polymerizers with volume more than 30 m3 have been used in China to produce nano-PVC resins,which are mainly used as chemical building materials.The structure characteristics of nano-PVC resin particles are introduced,and their thermostability,mechanical properties and rheological properties are studied.
