<p>[Problem] To provide a novel polyimide polymer which is soluble in an organic solvent and to provide a novel synthetic method for a polyimide polymer which does not pass through a polyamic acid with a low storage stability. [Solution] A polymer having a structure represented by formula (1). (In the formula: each R1 may be the same or different, and is independently an alkyl which may be substituted, an alkenyl which may be substituted, an aryl which may be substituted, an arylalkyl which may be substituted, or an arylalkenyl which may be substituted; each R2 may be the same or different, and is independently a hydrogen atom, a halogen atom, an alkyl which may be substituted, an alkenyl which may be substituted, an aryl which may be substituted, an arylalkyl which may be substituted, an alkoxy which may be substituted, an aryloxy which may be substituted, a perfluoroalkyl, a cyano, a nitro, or an ester; R3 is 1 to 4 same or different substituents that bind to a benzene ring and is independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl which may be substituted, an alkenyl which may be substituted, an aryl which may be substituted, an arylalkyl which may be substituted, an alkoxy which may be substituted, an aryloxy which may be substituted, a perfluoroalkyl, a cyano, a nitro, and an ester; X is a single bond, an alkylene which may be substituted, an alkenylene which may be substituted, an arylene which may be substituted, an arylalkylene which may be substituted, an oxyalkylene which may be substituted, an aryleneoxy which may be substituted; and n is an integer greater than or equal to 2.)</p> |
