Study on swelling properties of pectin-g-poly(acrylicacid-co-acry lamide)hydrogel

Zhang Xua

Abstract

A novel hydrogel of pectin-g-poly(acrylicacid-co-acrylamide) were synthesized by grafted copolymerization in aqueous solution. The swelling behavior of the hydrogel in distilled water were investigated. The results indicated that the swelling kinetic of the hydrogel could be divided into three stages;the swelling ratio of the hydrogel was the highest,then in the NaCl solution,lowest in the CuSO4 solution.
