摘要
综述了聚氯乙烯(PVC)树脂耐热改性和增韧改性的研究进展。PVC耐热改性方法主要有添加热稳定剂、交联、共混、共聚、氯化及无机纳米粒子改性;增韧改性的主要方法包括弹性体、纳米粒子、聚合物/无机纳米复合材料、纳米级微纤增韧以及原位聚合的方法。最后,提出了PVC耐热和增韧改性的发展方向。
Research progresses in modification of heat resistance and toughness of poly （vinyl chloride） （PVC） were reviewed. The heat resistance of PVC could be enhanced by adding heat stabilizers, crosslinking, blending, copolymerization, chlorination, and adding inorganic nanoparticles, etc. The toughness of PVC could be improved by blending with elastomer, nanoparticles and nanoscale micro fibers, and in-situ polymerization. The development trend of PVC modification was pointed out.
