POLYMER COMPOSITION FOR MAKING A MOISTURE-CURABLE IMMOBILIZING MATERIAL Russian patent published in 2020 - IPC C08L71/02 C08K5/5419 C08G63/66 

Abstract RU 2731266 C1

FIELD: medicine; technological processes.

SUBSTANCE: invention relates to a polymer composition used in medicine for making tires, bandages fixing bandages for limb and spinal immobilization in injuries and diseases of a human skeleton. Disclosed is a polymer composition for producing a moisture-curable immobilizing material, comprising a polyester, isocyanate, a catalyst. As polyester, it contains homopolymer of propylene oxide with molar mass of 3000, as isocyanate, it contains modified uretonimone 4,4'-diphenylmethane diisocyanate, as catalyst contains latent catalyst – mixture of triethylamine and oxalic acid in stoichiometric ratio, additionally contains gamma-aminopropyltriethoxysilane and vinyltrimethoxysilane.

EFFECT: increased stability during storage up to one year, increased antibacterial effect by 4 times, reduced bending stress by 2 times.
