Abstract: The neutralization of products which are phosphorus containing oligomers having ##STR1## linkages between phosphorus atoms and which are obtained by the self-condensation of .beta.-halo-alkyl esters of pentavalent phosphorus acids or by the condensation of these esters with an alkyl ester of a pentavalent phosphorus acid is accomplished by reaction with an alkylene oxide, either alone or in combination with water or an alcohol having the formula ROH where R is a C.sub.1 -C.sub.20 alkyl group, and is enhanced by heating the products with a Lewis acid to promote alcoholysis reactions between labile groups contained therein and structures formed by alkylene oxide neutralization of free acid groups. The stabilized product formed by this process gives a better cure when incorporated in a polyurethane foam.

Abstract: Stabilized 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 the condensation products of these esters with an alkyl ester of a pentavalent phosphorus acid are formed by terminating the condensation reaction when it is about 35-75% complete, said condensation being performed in the absence of a nucleophilic initiator, such as a sodium salt initiator. The lower degree of condensation in the product and the absence of the nucleophilic initiator during the condensation reaction, is responsible for the lesser degree of scorching in a polyurethane foam containing the product as compared to one which is formed by allowing the condensation reaction go to completion or by use of a nucleophilic initiator during the condensation.

The soluble portion of said products after recovery from the solvent can be incorporated in a polyurethane foam formulation to give a foam which will have less scorching than a foam containing the original condensation product that has not been extracted.

Abstract: 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 the condensation of these esters with alkyl esters of a pentavalent phosphorus acid are treated after residual acidity has been neutralized, e.g., with an alkylene oxide, with water and then with an alkylene oxide for a period of time which is sufficient to enable the water to open labile groups contained in the product and the alkylene oxide to neutralize any further acidity generated by the opening of such groups. The stabilized product formed by this process when incorporated to a polyurethane foam gives a foam having superior green strength to a polyurethane foam which is not treated in accordance with the invention.

Abstract: 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.
