综述PVC材料耐热性的研究

Reviews of studies on the heat resistant property of PVC materials

从共混、结晶、填充、交联、共聚、氯化以及提高分子质量等方面综述了改善PVC耐热性的各种途径,并对各种改性方法的优缺点和实施的难易程度进行了比较。

In this paper,metods of improving the heat resistance of PVC are reviewed in respects of blending,crystallization,packing,crosslinking,copolymerization,chlorination,and increase of molecular weight.And the advantages,disadvantages of each method is compared as well as the difficulties in implementation.
