Fluid polymer/polyol dispersions are prepared from novel polyether polyols.

Preparation of polymer polyols

A modified polyol, suitable for use as a non-aqueous dispersant in the preparation of polymer/polyols containing high levels of polymer, is provided. The modified polyol comprises the product obtained by reaction of a polyol with a coupling agent having at least two functional groups which are reactable with hydroxyl groups on the polyol. Suitable coupling agents include silicon compounds having two such functional groups, organic compounds having two or more alkoxy groups, saturated dicarboxylic acid derivatives, alkyl or aryl esters of carbonic acid, alkyl or aryl sulphonates, boric acid or its esters and titanates.
