| Abstract: | 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. |
