摘要
采用示差扫描量热(DSC)法测定了苯乙烯-马来酸酐共聚物(SMA)及其水解产物(HSMA)的玻璃化转变温度(Tg)。以Fox-Flory公式结合基团贡献法和改进的Couchman方程,对SMA和HSMA的Tg与其结构的关系进行了定量研究,理论计算结果与实验值吻合较好,表明提出的方程能适合SMA和HSMA两类聚合物的Tg估算。
The glass-transition temperatures (Tg) of hydrolytic styrene-maleic anhydride copolymers (HSMA) were determined with differential scanning calorimetry (DSC). Quantitative structure-property relationship (QSPR) of SMA and HSMA were studied by the Fox-Flory formula combined with group contri-bution method and improved Couchman equation. The calculation result matches the experimental data well. The obtained equations can be used to estimate Tg of SMA and HSAM.
