LIQUID POLYURETHANE COMPOSITION WITH TERMINAL EPOXY GROUPS Russian patent published in 2002 - IPC

Abstract RU 2190645 C2

FIELD: polymers. SUBSTANCE: invention relates to liquid polyurethane compositions with terminal epoxy groups that can be used as glues, sealing agents, coverings of different functional designation used in building and other branches of industry. Invention describes a liquid polyurethane composition with terminal epoxy groups comprising a product of copolymerization of glycerol and propylene oxide with molecular mass 4503-50003 Da, toluylenediisocyanate, glycidol and dibutyltin salt of saturated synthetic acids of C₁₀-C₁₃-fraction or dibutyltin salt of C₁₂-lauric acid as a stabilizing agent, 2-ethylhexanol, citric acid or aerosil and magnesium oxide. Invention ensures to obtain liquid polyurethane with terminal epoxy groups that can be solidified under atmosphere conditions. EFFECT: valuable properties of composition. 2 tbl, 6 ex
