| 摘 要： | 通过差示扫描量热仪(DSC)测定了橡胶填充油及其不同馏分的玻璃化温度.研究证实,橡胶填充油的组成与它的玻璃化温度存在一定的相关性:未分馏橡胶填充油的玻璃化温度,介于其饱和烃与芳香烃馏分各自的玻璃化温度之间;同时从分子结构角度用自由体积理论阐释了上述关系,目前有关橡胶填充油的玻璃化温度尚未见报道.

| Abstract: | The glass transition temperatures of extender oils and those different fractions were determined by means of Differential Scanning Calorimetry(DSC).The research made sure that the glass transition temperatures of extender oils and those fractions exist correlation:the glass transition temperatures of extender oils are between the glass transition temperatures of the saturated fractions and the glass transition temperatures of the aromatic fractions.At the same time,the research explained the above relation ... |
