Из полученного раствора отливают пленки и испытывают их, аналогично примеру 1. Устойчивость указанных композиций к действию УФ-лучей и повышение их эластичности приведены в табл.1. Таблица к1ус свойств пленок на основе ы-сополимер от длительности   methylene chloride with alcohol 9:11 The resulting filtering composition: 11g at the press filter and cast films on a glass substrate. The film thickness after drying is 0.135 mm. Irradiation is carried out with unfiltered light of the PRK-2 lamp at 60 ° C at a distance of 35 cm from the object. After irradiating the films, their physicomechanical tests for strength, elongation, double bending are carried out. EXAMPLE 2 A composition is prepared consisting of 4.25 wt.% Cellulose triacetate, 0.75 wt.% Copolymer; Dependence of the physicochemical composition of triacetate cel 95%,% methylene chloride with alcohol 9: 1. Films are cast from the resulting syrup and tested as indicated in Example 1. Example 3. Composite is prepared consisting of 1.25% by weight of copolymer, 3.75% by weight of cellulose triacetate and 95% of methylene chloride. alcohol 9: 1. Films are cast from the solution obtained and tested, analogously to Example 1. The stability of these compositions to the action of UV rays and an increase in their elasticity are given in Table 1.
