用DSC法研究了聚氨酯型吸水膨胀橡胶中水的状态，计算了各种状态水的分布及其与吸水结构单元之摩尔比。发现其亲水性聚醚的结构单元不同，其吸附水的状态和比例亦不同。

The states of water in the polyurethane type water swelling rubber was studied by means of DSC. The distribution of different water states and the relationships between water states and structure unit of hydrophilic polyether were investigated. It was found that the amount of nonfreezing water and the ratio of nonfreezing water versus ethenoxy unit on polyether is about 2 and the amount of nonfreezing water are about 1.5～2.0 times of bound freezing water.
