Abstract:
A resin material for denture base having two liquids comprising a liquid A and a liquid B, comprising the following components (a), (b) and (c):(a) a methacrylate or acrylate monomer having at least one unsaturated double bond, (b) one or more polymers selected from the group consisting of a methacrylate polymer, an acrylate polymer, a methacrylate/acrylate copolymer, a methacrylate/styrene copolymer, and an acrylate/styrene copolymer, and (c) a polymerization initiator, wherein the liquid A comprises the polymer (b), the monomer (a) wherein said monomer (a) has a solubility to the polymer (b) of 20% by weight or more, and the polymerization initiator (c); and wherein the liquid B comprises the polymer (b) and the monomer (a) wherein said monomer (a) has a solubility to the polymer (b) of less than 20% by weight; and when mixing the liquid A with the liquid B, the monomer (a) in the liquid A swells or dissolves the polymer (b) in the liquid B to increase its viscosity, whereby the mixture is polymerized and cured.
