| 摘 要： | 基于聚合物玻璃化转变的定义,探讨了聚合物宏观单晶体和聚合物单链单晶的玻璃化转变问题,指出玻璃化转变的温度依赖性不服从普适的Arrhenius方程,可以把WLF方程看作是聚合物玻璃化转变的特有温度依赖关系。介绍了二维状态下聚合物可能的玻璃化转变。

| Abstract: | The glass transition of macroscopic single crystal and single-chain crystal of polymer is discussed based on definition of glass transition. The temperature dependence of glass transition does not obey the general Arrhenius equation, on the other hand, WLF equation can be considered as a special temperature dependence of glass transition of polymer with segment motion. The glass transition of two-dimensional polymer film is introduced as well. |
