ABSTRACT:
An ionomer composite composition having improved and unique physical properties, includes a glass material containing at least one of divalent cations and multivalent cations; and at least one copolymer. The copolymer comprises: at least one hydrophilic monomer containing acid functional groups adapted to react with the at least one of divalent cations and multivalent cations to form ionic crosslinks among polymer chains, the hydrophilic monomer present in an amount sufficient to impart a desired degree of aqueous solubility to the copolymer, and at least one hydrophobic monomer present in an amount sufficient to impart a desired degree of structural stability to the composite composition when exposed to an aqueous environment.
