摘　　要：研究了添加新型复合稳定剂XWP-1的PVC材料的性能,确定了PVC材料基本配方,并利用不同弹性体对PVC材料进行了增韧改性。结果表明,新型复合稳定剂XWP-1提高了PVC的热稳定性,改善了其加工性能。弹性体Elvaloy741对PVC材料具有较好的增韧效果,但使PVC材料的热变形温度下降幅度较大。The properties of PVC materials added a new type of composite stabilizers XWP- 1 were studied. The basic compositions of the materials were determined. Different elastomers were used to toughening modify the materials. The results showed that the novel composite stabi- lizers increased the heat stability of PVC and improved its processability. Elastomer Elvaloy 741 showed better toughening effect on PVC materials but decreased their heat distortion temperature by a bigger margin.
