AbstractNovel graft copolymeric, pH responsive hydrogels have been synthesized by solution polymerization. Poly(methacrylic acid-g-ethylene glycol) hydrogels exhibit reversible complexation as a function of pH because of hydrogen bonding between the PEG grafts and the PMAA main chains. These gels are being developed as pH responsive membranes for use in biomedical applications. ATR-FTIR results indicate that there is hydrogen bonding occurring in membranes swollen under conditions favorable for complexation. Equilibrium swelling studies have shown that the pH of the surrounding environment has a significant effect on the swelling behavior of these membranes. The swelling behavior has also been shown to respond rapidly to changing pH conditions. P(MAA-g-EG) membranes also show pH sensitive permeability toward solutes as a result of this environmentally sensitive swelling.
