FIELD: organic chemistry.
SUBSTANCE: invention relates to polymers based on polyimide. A polymer based on polyimide is proposed for obtaining a polymer film containing a repeating unit selected from the group consisting of units represented by chemical formulas 3, 4 and 5. Also a polymer film for the manufacture of an optical device, including a cured polymer product based on polyimide, and an optical device obtained using it are proposed.
EFFECT: proposed polymer makes it possible to obtain a film with an excellent combination of transparency and heat resistance.
