METHOD FOR PRODUCTION OF POLYURETHANE FOAM Russian patent published in 1997 - IPC

Abstract RU 2076115 C1

FIELD: production of polyurethanes. SUBSTANCE: desired polyurethane foam is prepared by interaction of hydroxyl-containing polyether with poly(phenylene)-poly(methylene)polyisocyanate. Said interaction is carried out in the presence of catalyst, frothing agent and organosilicon froth stabilizer. Catalytically active oligoether being prepared by neutralization of suitable alkaline polymerizate with the help of glacial acetic acid is used as mentioned above hydroxyl-containing polyether. EFFECT: simplifies the method. 2 cl
