Abstract

PURPOSE: To prepare an acrylic resin having high solvent resistance and excellent melt flowability in molding, and keeping the original properties of the acrylic resin, by mixing two kinds of specific copolymers each composed mainly of methyl methacrylate and having different molecular weight.
CONSTITUTION: The objective acrylic resin composed of (A) ≥80wt% of a copolymer containing methyl methacrylate, (B) 2.5W10.0wt% of a copolymer having a molecular weight of ≥1,000,000, and (C) the remaining part of a copolymer having a molecular weight of ≤1,000,000, and having an intrinsic viscosity of 0.033W 0.100l/g, is prepared, e.g. by polymerizing methyl methacrylate, ≥2C alkyl methacrylate, and if necessary, an alkyl acrylate, wherein the polymerization is carried out by dissolving 2.5W10.0wt%, based on the total amount, of the polymer having molecular weight of ≥1,000,000 in the other monomers.
