Notes:
Compatibility and Thermal stability studies have been performed on PVC blends with chlororubber-20-graft polyblend-styrene-vinyl acetate-acrylonitrile (1:1:1) [CR-20gp-SVAAN (1:1:1)]. The grafting of styrene, vinyl acetate, and acrylonitrile onto chlororubber-20 backbone chain generates some amount of heterogeneity in the system. The compatibility behavior of PVC/CR-20gp-SVAAN (1:1:1) blends has been reflected in the ultrasonic velocity and absolute viscosity vs. composition plots of the blend. These blends have been found to be thermally miore stable than PVC/chlororubber-20 blends, but less stable than PVC/KM-365B blends. The rate of degradation is equal to that of the PVC/chlororubber-20 blends. The results have been discussed on the basis of compatibility, stabilizing, and destabilizing behavior of various component polymers with PVC matrix.
