FIELD: chemical industry, production of compositions for formation of films based on cellulose esters in particular, in production of manufactured fibrous and film materials. SUBSTANCE: aim is to increase light resistance of films of cellulose triacetate due to the fact, that polymeric composition has 8 - 10 mass % of cellulose triacetate, 0.008 - 0.16 mass % of oligoamides with molar masses of 400, 800 and 1000, that are products of polycondensation of soy-bean oil and fractionated polyethylenepolyamine esters, and up to 100 mass % of methylenechloride with ethanol mixture in volumetric ratio of 9 : 1. EFFECT: increased light resistance of cellulose triacetate films. 1 tbl |
