Abstract
Способ получения полисилоксануретана путем взаимодействия низкомолекулярного диола, органосилоксана и ароматического диизоцианата в среде апротонного растворителя, отличающийся тем, что в качестве низкомолекулярного диола используют блоксополимер на основе окиси этилена и окиси пропилена с молекулярной массой 4000-4500 и содержанием концевых гидроксильных групп 80-99 мас.% и калий(натрий)-алкоголятных групп 1-20 мас.%, в качестве органосилоксана используют циклотетрасилоксан формулы ! , где R-CH3, -C2H5, -C6H5, -CH=CH2, ! при мольном соотношении блоксополимера на основе окиси этилена и окиси пропилена, ароматического диизоцианата и циклотетрасилоксана 1:(10÷30):(3÷40), соответственно. A method of producing polysiloxanurethane by reacting a low molecular weight diol, organosiloxane and aromatic diisocyanate in an aprotic solvent, characterized in that a block copolymer based on ethylene oxide and propylene oxide with a molecular weight of 4000-4500 and a content of terminal hydroxyl groups of 80-99 wt is used as a low molecular weight diol. % and potassium (sodium) -alcoholate groups of 1-20 wt.%, cyclotetrasiloxane of the formula are used as organosiloxane! where R-CH3, -C2H5, -C6H5, -CH = CH2,! when the molar ratio of block copolymers based on ethylene oxide and propylene oxide, aromatic diisocyanate and cyclotetrasiloxane 1: (10 ÷ 30) :( 3 ÷ 40), respectively.
