Abstract A method is described that allows reduction of the amount of calcium phosphate phases deposited spontaneously inside poly(2-hydroxyethyl methacrylate) (PHEMA), a hydrogel of biomedical importance. PHEMA homo-interpenetrating polymer networks (homo-IPNs) were synthesized and then treated in a calcifying solution. A reduction of calcium uptake of 58 to 75% was measured by ICP emission spectroscopy in the IPNs as compared to the PHEMA homopolymer ( the parent network). The effect was rationalized in terms of reduction of the free volume available for the penetration and transport of Ca2+ and phosphate ions as a result of redundant chain packing through formation of IPNs.
