采用新型聚乙烯基甲基醚吸水凝胶（PVMEG），对温敏性吸水凝胶的动力学行为进行了实验研究。凝胶在310 K温度范围内表现出体积变化现象。在转变温度以下和转变温度以上，它分别膨胀和收缩。一个简单的数学模型的凝胶的动力学行为，它被发现，模拟的凝胶行为非常符合实验结果，通过采用适当的值包括在模型中的参数。
Kinetic behavior of a temperature-sensitive water-absorbing gel was analyzed experimentally by using a newly developed water-absorbing polyvinylmethylether gel (PVMEG). The gel showed a volume change phenomenon responding to a temperature change across the temperature of 310 K. It swelled and shrank respectively below and above the transition temperature. A simple mathematical model for the kinetic behavior of the gel is presented and it is found that the simulated behavior of the gel fits very well with the experimental results by employing appropriate values for the parameters included in the model.
