Abstract: 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 stabilizer, crosslinking, blending, copolymerization, chlorination, and adding inorganic nanoparticles, etc. The toughness of PVC could be improved by blending with elastomer, nanoparticles, and nanoscale micro fiber, and in-situ polymerization. The development trend of PVC modification was pointed out.

Key words: heat resistance, modification, toughening, research progress, poly (vinyl chloride)
