POLYMER MATERIAL Russian patent published in 2008 - IPC C09D127/16 C09D155/00 B32B33/00 C08L27/06 C08J7/04 

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%).
