Water sorption and water binding properties of crosslinked polyacrylamides: effect of macromolecular structure and crosslinking

Abstract
The water binding properties of crosslinked copolymers of acrylamide with tetraethyleneglycol diacrylate triethyleneglycol dimethacrylate, N,N′‐methylene bisacrylamide and divinylbenzene were investigated. It was observed that the freezing water contents of these copolymers depend on nature of the monomers and crosslinkers, as well as on the extent of crosslinking.
