摘要：

A ternary blend consisting of chlorinated polyethylene (CPE), poly(vinyl chloride) (PVC) and epoxidized natural rubber (ENR) was investigated to define the miscibility regime. The techniques used were mainly dynamic mechanical analysis and tensile testing. In this ternary blend where ENR plays the role of the compatibilizer, it was established that different amounts are required to cause miscibility for different ratios of CPE/PVC; the highest at equal concentrations of the chlorinated components. Depending on the PVC/CPE ratio and the amount of compatibilizer, a wide spectrum of mechanical properties was obtained. Based on the single glass transition temperature data, a ternary phase diagram was constructed and the results were found to correlate well with the spinodal curve calculated for this system using a modified version of the Flory-Huggins lattice theory suitable for ternary blends.
