固相法CPE非晶相中氯含量的WAXD法测定

DETERMINATION OF CHLORINE CONTENT IN THE AMORPHOUS PHASE OF CPE FROM SOLID-PHASE CHLORINATION BY WAXD METHOD

本文采用迭代法对固相氯化法氯化聚乙烯(CPE)的广角X射线衍射(WAXD)数据进行处理,同时获得了固相法CPE非晶相含量和非晶相中氯含量的定量数据。实验结果表明:对于表现氯含量为2.1％～12.0％的CPE,其非晶相含量是原料PE的1.9～3.4倍,非晶相中的氨含量是表观氯含量的1.7～3.0倍。

The WAXD data of chlorinated polyethylene (CPE) from solidphase chlorination was handled by iterative method, and the quantitative data of the content of amorphous phase in CPE and that of chlorine in amorphous phase in CPE were obtained. The results show that the ratio of the content of amorphous phase in CPE to that in PE is 1.9-3.4, whereas the ratio of the chlorine content in amorphous phase in CPE to that in CPE is 1.7-3.0.
