Abstract
A normally liquid, flame retardant polyol ester prepared by a process comprising reacting a halogen containing anhydride of a dicarboxylic acid or a mixture of said anhydrides with an aliphatic polyol having at least three hydroxy groups and an aliphatic diol, to obtain a substantially fully esterified halogen containing product in which the acid number does not exceed 10, with the optional removal of unreacted diol during the course of the reacting or subsequent to the reacting. This flame retardant polyol ester may be used in the preparation of polyurethanes or polyesters.
