ABSTRACT:
A method of preparing fiber reinforced acrylic thickened compositions which can be molded under low pressures and temperatures to provide thermoset articles, wherein liquid reactive components are slowly absorbed in high molecular weight solid acrylic resin in the form of large particles. The acrylic resin functions as a thickener which delays the viscosity build allowing fiber reinforcement to be incorporated before molding. The molding composition is well suited for use in dentistry and other fields where small amounts or molding composition are used occasionally.
