説明

The synergetic effect of saponificated poly (vinyl acetate) s (SPVAc) with zinc stearate/calcium stearate synergetic soap on the thermal stabilization of poly (vinyl chloride) (PVC) was investigated by calorimetry. A marked synergetic effect was observed by compounding SPVAc as a solution. In particular, the lower saponificated SPVAc exhibited the measurable effects even when they were added as a solid. The synergetic effects of SPVAc was superior to those of poly (vinyl alcohol), owing to the better compatibilities with PVC. The values obtained for relationships involving NCG (distance to nearest center of gravity) or area for SPVAc particles in the compound PVC and the amounts of SPVAc added were useful parameters to evaluate the dispersion degree of additives in compound plastics.
