Abstract (en)

[origin: WO2021001229A1] The present invention relates to a method for producing an amine-based polyol by reacting a tertiary amine with various epoxides in several steps. The invention further relates to the amine-based polyol obtained by means of this method and to the use of the amine-based polyol in producing polyurethanes, wherein the polyurethanes are preferably synthesised on the basis of toluylene diisocyanate (TDI) and are preferably moulded foams.
