An oxyalkylated product useful for making polyurethane foams is prepared by reacting an alkylene oxide with a heated mixture of a phenol and a non-phenolic active hydrogen compound, at least one of which can be halogenated, in the presence of a catalyst complex of a phenol and an iron or aluminum substance. The mixture can also include a neutral phosphorus compound and/or acid anhydrides to enhance flame retardant properties. Optionally, also, the oxyalkylation reaction can be terminated by adding a tri (lower alkyl) amine and alkylene oxide to react with residual phenolic hydrogen in the mixture.
