ABSTRACT:
Novel (halo)(hydroxy)-substituted phosphorus-containing acid derivatives are disclosed. Preferred compounds are 2-halo-3-hydroxypropyl ester derivatives of phosphorus and phosphoric acid formed by reaction of at least some amount of tertiary butyl glycidyl ether with a halogenated derivative of a phosphorus-containing acid followed by acid dealkylation of the product. The polyol products are useful in the production of polyurethane articles such as foams having increased resistance to the effects of fire. The derivatives can be additives or reactants in the polyurethane, depending on the presence or absence of terminal hydroxyl groups within the given ester moieties.
