Abstract
Sucrose-based polyether polyols which do not promote degradation of HCFC blowing agents are produced by blocking at least 10% of the polyol's hydroxyl groups with a compound represented by the formula CH.sub.3 COCH.sub.2 COOR in which R represents an alkyl group. These polyether polyols are particularly useful in the production of polyurethane foams.
