摘要：
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., 16:120-126, 2010. (C) 2010 Society of Plastics Engineers
