Abstract

The method to regulate the degradation kinetics of ionically crosslinked gels via controlling the dissociation rate of the polymer chains was discussed. It was observed that the initial physical properties of the varying hydrogels were quantified with the compressive elastic moduli (E) and swelling ratios (Q) of the gels. It was also observed that the crosslink junctions composed of the G blocks with an equivalent MWG were highly stable against ion exchange. It was found that the kinetics of the ion-exchange process and gel degradation could also be controlled by the fraction of the crosslinked junctions in the gel processing a size mismatch.
