POLYMERIC COMPOSITION Russian patent published in 2003 - IPC

FIELD: polymers. SUBSTANCE: invention relates to polymeric composition based on chlorovinyl polymers and polyurethanes. Invention describes polymeric composition comprising the following components, mas. p. p.: chlorovinyl polymer, 5-100; polyurethane and/or polyurethaneurea, 5-100; plasticizing agent, 0.01-65; stabilizing agent, 0.01-3; lubricant, 0.01-1.5; and filling agent, 0.01-2.5. Polyurethane and/or polyurethaneurea in finely-dispersed form with content of free isocyanate groups 0.8-6.0% is prepared by dispersing block oligomer in an aqueous medium that is synthesized on the base of oligodiol, diisocyanate and low-molecular lengthener chain with active hydrogen atoms. Invention provides preparing materials exhibiting the enhanced strength indices due to the improvement of polymers compatibility. Compositions can be used for making film materials, artificial leather, glues, binding agents, coatings, structural materials, articles for medicinal designation. EFFECT: improved preparing method, valuable properties of composition. 3 tbl, 16 ex
