Zusammenfassung:	Provided as novel compositions are: (1) unsaturated cycloaliphatic ester polyols prepared by the reaction of a monounsaturated cycloaliphatic carboxylic acid anhydride, a polyhydric alcohol and an alkylene oxide, and (2) brominated derivatives of said polyols. The brominated cycloaliphatic ester polyols of the invention are useful as flame-retarding agents and are especially suitable for use in the manufacture of flame-retarded cellular polyurethanes including flexible foams.
