摘    要:本文用Van Krevelen方程和Mettler DSC30分别计算和测得聚对苯二甲酸丁二酯的克分子热容。从不同温度下的克分子热容的计算值和实验值,确定了焓,熵和吉普斯自由能。结果表明,只有在一定的温度范围内,上述热力学函数的计算值和实验值才吻合的较好。

关 键 词:热力学性质  聚对苯二甲酸丁二酯  Van Krevelen方程

Abstract:Molar heat capacity of poly(butylene terephthalate) is calculated with the Van Krevelenls equation's,and measured by Mett DSC 30.According to the values of molar heat capacity from the calculations and experiments at differient temperatuies,enthalpy,entropy and Gibbs free energy are determined. The results show that the better agreements between the calculated and experimental values of above thermodynamic function can be reached only in a certain temperature range.
Keywords:thermodynamic properties  poly (butylene terephthalate)  Van Krevelen equations
