PROCESS FOR PREPARING HYDROXY CONTAINING COMPONENT FOR MANUFACTURE OF MOLDED ELASTIC POLYURETHANE Russian patent published in 1997 - IPC

Abstract RU 2076877 C1

FIELD: chemistry of polyurethanes; more specifically furniture and automotive industries. SUBSTANCE: claimed process makes it possible to retain stability of hydroxy- containing components with respect to viscosity and eliminate triethylamine, tall oil and oligoethers having molecular weight of 3000-3600, foamed organosilicon regulator is oxyalkyleneorganosiloxane block copolymer, and nitrogen-containing catalyst includes mixture of 1,4- diazobicyclo [2,2,2]octane with dimehylethanol amine at optimum ratio of ingredients and stepwise stirring of said ingredients. EFFECT: more efficient preparation process. 2 tbl
