| description | Producing polyether polyols by catalytic ring-opening polymerization of at least one alkylene oxide having at least one Zerewitinoff-active compound Z1 and optionally at least one Zerewitinoff-active compound Z2, comprises (i) using at least one cyclic compound A that contains nitrogen and amine compound (I), and (ii) heating (I) for a time period of 5-30 minutes, preferably 10-25 minutes at a temperature of 140-180[deg] C, preferably 150-170[deg] C, and optionally performing a dosage of the alkylene oxide in the presence of Zerewitinoff-active compound Z2. Producing polyether polyols by catalytic ring-opening polymerization of at least one alkylene oxide having at least one Zerewitinoff-active compound Z1 and optionally at least one Zerewitinoff-active compound Z2, comprises (i) using at least one cyclic compound A that contains nitrogen and amine compound of formula (I), and (ii) heating (I) for a period of 5-30 minutes, preferably 10-25 minutes at a temperature of 140-180[deg] C, preferably 150-170[deg] C, and optionally performing a dosage of the alkylene oxide in the presence of Zerewitinoff-active compound Z2. R1, R2 : alkyl or aryl; and R3, R4 : H, alkyl or aryl, where R1, R3 and R3, R4 or R2, R4 form a ring together with the Zerewitinoff-active compound or its mixture. An independent claim is included for polyether polyols produced by the method. |
