PROCEDURE FOR THE PREPARATION OF POLYETERPOLIOLES. |
abstract |
The invention relates to a process for producing polyethercarbcinatopolyols in which (i) in a first stage a polyethercarbonate polyol is produced from one or more initiating substances with H functionality, one or more alkylene oxides and carbon dioxide in the presence of al minus a DMC catalyst, and (ii) in a second stage the polyethercarbonatopolyol chain is extended with a mixture of at least two different alkylene oxides in the presence of at least one DMC catalyst. The invention also relates to polyether carbonate polyols containing a mixed terminal block of at least two alkylene oxides and to a process for producing soft polyurethane foams, in which a poly component containing a polyether carbonate polyol according to the invention is used. |
