FIELD: polymer materials. ^ SUBSTANCE: invention provides polymer material with protective coating for upholstery simulated leathers characterized by reduced combustibility. Polymer material obtained from polyvinylchloride, di-2-ethylhexyl phthalate, pyrocatechol, zinc oxide, and pigment further contains protective coating obtained from dimethylformamide solution of mixture of pyperilene/acrylonitrile/methacrylic acid copolymer (monomer unit ratio 40:50:10) and copolymer of 60-50% vinylidene difluoride and 40-50% tetrafluoroethylene. ^ EFFECT: (at optimal contents of copolymers) avoided migration of plasticizer, reduced burning rate so that material extinguishes earlier than burning attains measuring base , and reduced abrasion (by 40-50%). ^ 1 tbl, 4 ex |
