説明
Synergetic effect of ethylene-vinyl alcohol copolymers (EVOH) with zinc stearate/calcium stearate synergetic soap on the thermal stabilization of poly (vinyl chloride) (PVC) was investigated by colorimetry. Under the present conditions, a marked synergetic effect was observed by compounding EVOH as a solution. But the systems compounding EVOH as a solid did not exhibit any marked effects. In particular, more easily measurable effects were observed with increasing hydroxycontent of EVOH as a solution. The image processing evaluation of the dispersion degree showed that EVOH were finely dispersion into PVC by compounding as a solution, while solid EVOH did not exhibit fine dispersion. These results suggest that the effects of EVOH are markedly dependent on their dispersion degree in PVC compounds. Some values obtained for relationships involving NCG (distance to nearest center of gravity) or area of EVOH particules in the compound PVC and amount of EVOH added were useful parameters to evaluate the dispersion degree of additives in compound plastics.
