Abstract
PURPOSE: The titled compositon, prepared by incorporating a powdery polymer obtained by mixing methyl methacrylate polymers having different molecular weight with a liquid monomer, having the great plasticity of the resultant mixture and prolonged time of the plastic state in filling in a gypsum mold, and capable of reducing the dental technical operation time.
CONSTITUTION: Methyl methacrylate polymers, having different molecular weights, and consisting of 30W70wt% low-molecular weight one, rapidly swelling and dissolving in a liquid monomer, and having an average molecular weight of 50,000W200,000 and 70W30wt% high-molecular weight one having a molecular weight of 300,000W800,000, and slightly swelling and dissolving in the liquid monomer as a powdery polymer are mixed with a polymerizable monomer at a weight ratio of preferably 2:1 to give the aimed resin composition for the denture base. The resultant composition can be used in a softer gypsum mold than in the conventional one, and the polymerized material after the thermal polymerization can be easily taken out of the mold. Problems, e.g. the breakage of the denture, in taking out thereof are solved.
