FIELD: polymer materials. SUBSTANCE: in particular, invention relates to preparation of concentrated solutions of esters of cellulose and ether- cellulose with carboxylic acids. Multicomponent polymer composition for manufacturing triacetate films includes 8-10 wt % of cellulose triacetate with acetyl number 61.8%, 0.01-0.1 wt % of 2- hydrazyl-3-mercaptoquinoxaline as modifying additive, and organic solvent: mixture of methylene dichloride with ethanol at volume ratio 9:1 (to 100%). Invention increases light resistance of film: number of ruptures in macromolecules after UV irradiation decreases by several times. EFFECT: improved consumer and working characteristics of film. 1 tbl, 12 ex
