摘要：

Analysis of the states of water in polyacrylamide gel and its cross-linked gel was done by the measurements of the spin-lattice relaxation time T1 and the amount of unfrozen water at -35 °C. It was found that the T1 of water was reduced and the amount of unfrozen water was increased with an increase in extent of polymerization and cross-linkage of the gels. The results obtained much depend on the nature of the gel, which is characterized by the size of space in the gel. © 1979, American Chemical Society. All rights reserved.
