  • Published:
Polymer Bulletin Aims and scope Submit manuscript

Summary

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.
