ABSTRACT:
Brominated ester-containing polyether polyols are prepared by the sequential reaction of a polyether polyol with 4,5-dibromohexahydrophthalic anhydride or its corresponding diacid and an alkylene oxide. The resulting polyols are particularly useful in the preparation of flame-retardant polyurethane foams.
