Manufacturing method of polyimide film |
abstract |
The present invention is a polyimide film that is imidized by heating and drying the solution obtained by adding a dehydrating agent and an imidization catalyst to a polar organic solvent solution of a polyimide precursor obtained from a tetracarboxylic dianhydride compound and a diamine compound. In the method for producing a polyimide film, wherein the imidation catalyst is diethylpyridine, a polyimide film having high productivity and good film quality such as mechanical properties and adhesive strength can be obtained. . |
