Process for the manufacture of polyether polyols and their use for preparing polyurethanes

Process for the manufacture of a polyether polyol by reaction between an organic compound containing 2 or more active hydrogen atoms in the molecule and an alkylene oxide in the presence of a catalyst comprising a tertiary amine NRR'2, in which R is a cycloalkyl or cycloalkenyl group and each R...

Zusammenfassung:Process for the manufacture of a polyether polyol by reaction between an organic compound containing 2 or more active hydrogen atoms in the molecule and an alkylene oxide in the presence of a catalyst comprising a tertiary amine NRR'2, in which R is a cycloalkyl or cycloalkenyl group and each R' may be an alkyl, cycloalkyl or cycloalkenyl group, polyether polyols so manufactured, process for producing polyurethanes by reacting said polyether polyols with isocyanate, and polyurethanes so produced.
