Abstract
Interpenetrating polymer networks of poly(2-hydroxyethyl methacrylate) and poly(ethylene oxide) were synthesized by the free radical copolymerization of 2-hydroxyethyl methacrylate and ethylene glycol dimethacrylate in aqueous solutions of poly(ethylene oxide) diglycidyl ether (PEODGE), followed by amine−epoxy coupling reactions within the resultant gel network. The effects of ethylenediamine and PEODGE concentrations and coupling methods were examined and are discussed in this paper. Swelling studies and cryogenic-SEM analysis showed that these novel networks have high water intakes (equilibrium water content >3) and pore sizes on the order of up to 1 μm.
