NOUVEAUX AMINOALCOOLS DITERTIAIRES ET LEUR UTILISATION EN TANT QUE CATALYSEURS DANS LA PREPARATION DE MOUSSES DE POLYURETHANNES.CES COMPOSES REPONDENT A LA FORMULE(CF DESSIN DANS BOPI)DANS LAQUELLE R REPRESENTE L'HYDROGENE OU UN GROUPE METHYLE ET Y UNE LIAISON SIMPLE OU UN GROUPE METHYLE. CES COMPOSES SONT UTILISES AVANTAGEUSEMENT COMME CATALYSEURS DANS LA PREPARATION DE MOUSSES DE POLYURETHANNES A PARTIR D'UN POLYOL ET D'UN POLYISOCYANATE. New ditertiary aminoalcohols are useful as catalysts in the preparation of polyurethane foams. The new catalysts are particularly stable in the presence of polyols and other components often used in the conjunction with such polyols.
