Abstract: Polyvinyl chloride(PVC)has been blended with solid stated chlorinated polyethylene(CPE). The dependence of the compatibility of the blends on the mixing methods,chlorine content in CPE has been investigated.The dynamic mechanical analysis results showed that the PVC/CPE blends are partially compatible. The compatibility of the blends increases with increasing chlorine content in CPE and is affected by methods of blending. The CPE having continual segments showed a better compatibility with PVC. The morphology of the blends showed that CPEs are distributed on the surface of the PVC particle in a form of continual network.

Key words: PVC, chlorinated polyethylene, blend, compatibility
