摘要：
A pentacomponent acrylate copolymer containing hydroxyl and carboxyl groups was grafted with a semi-blocked polyurethane prepolymer and then deblocked to get polymer network with carboxyl groups. The network polymer can swell at pH range 6-13 and swell has reversible characteristic up to pH 11.Moreover, swelling kinetics is belong to a non-Fickian type.
