【摘要】 对聚氯乙烯(PVC)树脂耐热改性方法的研究进行了综述。PVC树脂耐热改性方法有共混改性、共聚 合改性、氯化改性和其他改性。各类改性方法均能使PVC的耐热性能有不同程度的提高,且加工性能和抗冲击性能 也有一定程度的改善。更多还原

【Abstract】 The methods for modifying heat resistance of poly(vinyl chloride) (PVC) resins were reviewed, including blending modification, copolymerization modification and chlorination modification, etc.. The methods were capable to not only raise the heat resistance of PVC resins to different extents, but also improve their processability and impact resistance to certain extent.更多还原
