ABSTRACT:
The invention relates to highly reactive polyoxyalkylene-polyols prepared by oxyalkylation of an initiator molecule containing, in bonded form, at least 2 reactive hydrogen atoms and at least one tertiary amino group bonded via a spacer bridge, which preferably comprises an alkylene radical having at least 3 carbon atoms, by means of at least one alkylene oxide, preferably ethylene oxide and/or 1,2-propylene oxide, to a process for the preparation of these polyoxyalkylene-polyols, and to their use for the production of compact or cellular, preferably flexible polyisocyanate polyaddition products.
