| 摘 要： | 用热释电流(TSC)法研究高聚物驻极体的玻璃化转变。以有机玻璃作材料,研究了极化电场强度、极化时间、极化温度和升温速率等实验条件对热释电流的影响。在此基础上,研究了聚氯乙烯-聚氨酯共混物的相容性,TSC谱图表明该共混物为一个部分相容体系。

| Abstract: | The thermally stimulated current (TSC) method has been used in study ofglass transition of polymer electrets. The influence of the experimental conditions,include poling fields, poling time, poling temperiture and heating rates, on the TSGof PMMA was invertigated in detail. The miscibility of PVC-PU polymer blendshas been studied by TSC. The TSC specturm of PVC-PU blends indicate that PVC-PU is a partical compatibility system. |
