A Study on the Antiplasticization of Polyvinylchloride
PVC의 역가소화 기구에 관한 연구
Abstract
Influence of dioctyl phthalate (DOP) on the physical properties of polyvinylchloride (PVC) were examined, and the antiplasicization mechanism was inv estigated by measuring dynamic mechanical properties and specific volume. Above the glass transition temprature (Tg), small amount of DOP plasticized PVC but an antiplasticizing was observed below Tg. The antiplasticization effect was more pronounced at lower temperatures. DOP seemed to suppress the mobility of PVC chains in the glassy state. Annealing appeared to suppress the relaxation of PVC chains further. Both antiplasticization and annealing widened the spread of
