PROCESS FOR POLYIMIDE RESIN AND POLYIMIDE FILM USING THE SAME

摘要

The present invention relates to a manufacturing method of a polyimide resin and a polyimide film manufactured using the same. More specifically, the present invention relates to a manufacturing method of a polyimide resin, which polymerizes diamine and different kinds of dianhydride; and to a polyimide film manufactured using the polyimide resin. According to the present invention, provided are the manufacturing method of the polyimide resin and the polyimide film manufactured using the same, wherein the manufacturing method of the polyimide resin comprises the steps of: dissolving diamine in a solvent to form a first solution; mixing the first solution with dianhydride represented by chemical formula 1 and dianhydride represented by chemical formula 2 to form a second solution including polyamic acid (PAA); and thermally treating the second solution.
