ABSTRACT:
Glass ionomer cements for dental restoratives with improved physical properties are produced by the present invention. Acryloyl and methacryloyl derivatives of amino acids are used in the invention to copolymerize with acrylic acid, methacrylic acid or various acrylic acid-comonomer mixtures to produce water soluble polycarboxylic acids.
