摘要： Products which are phosphorus containing oligomers having ##EQU1## linkages between phosphorus atoms and which are obtained by the self-condensation of .beta.-haloalkyl esters of pentavalent phosphorus acids or by condensation of these esters with an alkyl ester of a pentavalent phosphorus acid are treated after residual acidity has been neutralized with an alkylene oxide for a period of time which is sufficient to enable the alkylene oxide to act upon labile groups contained in the condensed product, i.e., cyclic, pyro and bridged groups, and to neutralize any further acidity generated by the opening of such groups. The stabilized products formed by this process when incorporated in a polyurethane foam formulation produce a foam having superior green strength to a foam containing such products which have not been treated in accordance with this invention.
