PURPOSE: A manufacturing method of the acrylic copolymer is provided to have a plurality of carboxyl group and epoxy group in a molecule, to have excellent storage stability, and to manufacture a copolymer useful for manufacturing an one component type thermosetting adhesive or an optical coating film. CONSTITUTION: A manufacturing method of a acrylic copolymer, which is in the chemical formula 1 and has carboxyl group and epoxy group at the same time, comprises a step of adding 1,2-dimethoxyethane during polymerization of copolymer. In the chemical formula 1, R1, R2 and R3 is hydrogen or methyl group, and R4 is C1-20 alkyl, aryl, alkylaryl, cycloalkyl or multi cycloalkyl. The acrylic copolymer is used for the manufacturing of an adhesive for FPCB or an optical coating film. |
