Abstract
Haze-free reactive flame retardant halo polyols are made by reacting (a) a halogen containing cyclic acid anhydride (e.g. tetrabromophthalic anhydride), (b) an aliphatic polyol, e.g. diethylene glycol, and (c) an epoxide, e.g. propylene oxide, and including potassium salt of fatty acids (e.g. potassium acetate) in the reaction mixture in an amount at least sufficient to neutralize residual sulfuric acid that is usually present in the halogen containing cyclic acid anhydride.
