摘要
通过对非晶聚氯乙烯α内耗峰峰温与测量频率的实验结果的拟合，提出了一种新的玻璃化转变附近弛豫时间的表达式，不仅很好地拟合了实验结果，给出调节参量合理的物理意义，而且为Ｋａｕｚｍａｎｎ疑题（ｐａｒａｄｏｘ）提供了一个合理的解决．
A new relationship between relaxation time and temperature through the rubber glass transition in amorphous polymers is proposed, by fitting the dynamic mechanical data of amorphous PVC. A satisfactory agreement between experimental data and theory is obtained, and clear physical meaning is given for each parameters. Especially, this relationship provides a reasonable resolution for Kauzmann paradox.
