TENSILE PROPERTIES AND INTERDIFFUSION OF VINYL CHLORIDE POLYMERS AND POLY(ε-CAPROLACTONE) BLENDS

摘要

The tensile properties of. blends of poly(ε-caprolactone) (PCL) with vinyl chloride polymers having different chlorine content (56.8%, 63% and 67%) were studied. It was found that the tensile properties are dependent on the chlorine content of the vinyl chloride polymer as well as the composition of the blends. Similar trends of compositional dependence of the properties were observed for the three blend systems. In addition, the interdiffusion between PCL and vinyl chloride polymers was qualitatively estimated. The vinyl chloride polymer having lower chlorine content possesses higher interdiffusion with PCL.
