Abstract: Solid state chlorinated polyethylene(CPE) was used as compatibilizer for PVC/LLDPE blends. The effects of the composition of blends and the molecular structure of CPE on mechanical properties of the blends were investigated. The mechanism of CPE as a compatibilizer for PVC/LLDPE blends was interpreted by correlating the structure of CPE with morphology of the blends revealed by SEM, TEM and DMA. The experimental results showed that the compatibility between PVC and LLDPE and the mechanical properties of the blends were improved by the addition of CPE.

Key words: polyvinyl chloride, linear low density polyethylene, blend, compatibility, compatibilizer
