Mechanical Properties of Styrene Acrylonitrile and Chlorinated Polyethylene Blends: Effect of Chlorine Content

Abstract

Abstract:The mechanical properties of binary blends of styrene acrylonitrile (SAN) and chlorinated polyethylene (CPE) were investigated. Blend compositions ranging from pure SAN to CPE, in 10% increments, in solution, and used to investigate mechanical properties as a function of compositions, chlorine (Cl) content in CPE and temperatures. In general, the mechanical properties of the SAN/CPE blends were found to be between the values of the corresponding pure components. Comparison of the yield stress and modulus of the blends with Cl content in CPE showed that these properties are in decreasing order: SAN/CPE(25%), SAN/CPE(36%), SAN/CPE(42%) and SAN/CPE(48%). For any blend composition, Young's modulus decreases with temperature and levels off at and above ~100 o C.
