PURPOSE:To obtain a methacrylic resin having improved solvent resistance, by copolymerizing methyl methacrylate with a (meth)acrylamide monomer. CONSTITUTION:Methyl methacrylate is copolymerized with 0.1-50wt% (meth) acrylamide shown by the formula (R1 is H, or methyl; X is H, methyl containing <=4C saturated alkoxy as a substituent group) such as (meth)acrylamide, N- methoxy-methyl(meth)acrylamide, N-propoxymethyl(meth)acrylamide, etc., to give the desired methacrylic resin.
