PROCESS FOR PREPARING A POLYURETHANE FOAM

Document Type and Number:

WIPO Patent Application WO/2011/026989

Kind Code:

A3

Abstract:

The invention relates to a process for preparing a polyurethane foam, wherein a polyether polyol and a polyisocyanate are reacted in the presence of: a blowing agent; of from 1 to 30 ppmw, based on the polyether polyol, of metals derived from a composite metal cyanide complex catalyst; and of from 0.5 to 100 ppmw, based on the polyether polyol, of a phosphoric acid compound comprising a phosphoric acid selected from orthophosphoric acid, polyphosphoric acid and polymetaphosphoric acid, and/or a partial ester of such a phosphoric acid.
