| Abstract: | The states of water in the partiallyhydrolysized polyacrylamide 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 functional group were investigated. It is found that a mol of water absorbing groups in PHPAM WSR can absorb about 4 mol nonfeezing water and the amount of bound freezing water are about 1.5 ~ 2.0 times of nonfreezing water. Crosslinking level affectes the total amount of water and thus the amount of free water in WSR. But crosslinking level and rubber matrix of WSR do not affected the amount of nonfreezing water in WSR. |
