PREPARATION METHOD OF COLORLESS AND TRANSPARENT POLYIMIDE FILM

摘要

polyimide catalyze the polyamide acid solution obtained from the polymerization reaction of a diamine and dianhydride organic solvents and by the addition of a dehydrating agent in the method of coating and drying to form a film behind which a polyimide -forming reaction producing a colorless transparent polyimide film , reaction between the raw material and the catalyst suitable to reduce the production efficiency of the existing complicated process steps through the content control increase the cost can be minimized .
