The results were as follows. The processability of graft copolymers was better than that of PVC and PVC/CPE blends, and gradually improved with increasing CPE content.

结果表明：接枝共聚物的加工性能优于PVC和PVC/CPE共混物，且其加工性能随CPE含量增加而逐渐改善；

X ray pattern of Cl element in the HBP/PP/PVC and PP/PVC blends were detected and vantage software was applied to calculate the average diameter and to make statistics of particle distribution.

通过X射线能谱微区分析得到了共混物中氯元素面分布图，对氯元素面分布进行了粒径分布统计和平均粒径计算。

The results showed that the mechanical properties of blends of PVC and PTW decreased compared with PVC itself.

结果表明：加入PTW将导致体系的力学性能降低；
