| Abstract | 57 ABSTRACT Self-curing compositions are prepared based on poly methyl methacrylate (PMMA) are by mixing a finely powdered solid polymer phase of PMMA and/or poly (2-hydroxyethyl methacrylate) (PHEMA) with a liquid monomer phase of methyl methacrylate (MMA) and/or 2-hydroxyethyl methacrylate (HEMA) in a weight ratio of polymer phase to monomer phase of 1.5 to 3.3:1 wherein the portion of PHEMA in the cured product is between 2 and 99 weight %. The product is prepared by vigorously stirring the mixture at room temperature until the polymerization is essentially finished. |
