Base-catalyzed long-chain active polyether from short-chain DMC catalyst initiator |
| abstract |
The present invention provides a long chain active polyether polyol characterized by a functionality of 2-6 and an equivalent weight of 1000-2200 Da. Such long chain polyethers comprise (1) an initiator composition having an equivalent weight of 350 Da or less and (2) one or more alkylene oxides to which up to 20% ethylene oxide may be added as a cap, (3) Including the alkoxylation product in the presence of at least one basic catalyst. A suitable initiator composition (1) comprises (a) a low molecular weight polyether having a functionality of 3 and an equivalent weight of less than 350 Da, (b) at least one low molecular weight initiator compound comprising glycerin, and (c) (D) an alkoxylation product of propylene oxide or a mixture of propylene oxide and ethylene oxide in the presence of at least one double metal cyanide catalyst. A method for producing such a long chain polyether polyol is also disclosed. |
