The present invention relates to a method for producing an imide substituted copolymer resin having excellent transparency and heat resistance. The present invention relates to a mixture of an unsaturated dicarboxylic anhydride monomer and a solvent, a methacrylic acid ester monomer, an initiator and a chain transfer agent in a batch reactor. Separating and adding to copolymerize; And continuously supplying a mixture of a primary amine and an imide substitution reaction active catalyst to a batch reactor that has undergone the copolymerization step to perform an imide substitution reaction. To provide.n n n The imide substituted copolymer resin prepared by using the method for preparing an imide substituted copolymer resin according to the present invention has excellent transparency and heat resistance, thereby maintaining an overall balance of physical properties and having a high melt index, thereby providing excellent processability.n n n Methacrylic acid ester, unsaturated dicarboxylic anhydride, unsaturated dicarboxylic acid imide, imide substitution |
