Abstract: A methacrylic resin having excellent impact resistance which is industrially more usable in general purposes, has the excellent weatherability and surface gloss inherent in methacrylic resins, and is optionally excellent in transparency and other properties. The impact-resistant methacrylic resin is characterized by being constituted of (A) a partially hydrogenated conjugated diene polymer having a degree of hydrogenation of from 20% to 70%, excluding 70%, and (B) a methacrylic copolymer formed from from 80 to 99.9% by weight-methyl methacrylate and from 0.1 to 20% by weight at least one other vinyl monomer-copolymerizable with the methyl methacrylate, and by having a toluene-insoluble content of from 0.5 to 50% by weight and a degree of swelling in toluene of from 2 to 12.
