| Abstract: | Correlations of the stress‐strain behavior and impact strength of poly(vinyl chloride) (PVC) blends with different amounts and chlorine contents of solid‐state‐chlorinated polyethylene (CPE) were studied. The relationships between the morphology and properties of the PVC/CPE blends also were investigated. The results of dynamic mechanical analysis and transmission electron microscopy showed that PVC/CPE blends are partially compatible systems and that a certain interaction exists between the two phases. When the amount of CPE (chlorine content, 36–42%) was 7–15 phr (parts by weight per hundred parts of resin), an essentially perfect CPE network was formed, and the blends showed better impact resistance. A Brabender Plasticorder study revealed that CPE can promote the plasticity of PVC and improve its processability. J. VINYL ADDIT. TECHNOL., 2010. © 2010 Society of Plastics Engineers |
