US Patent:

39594157, May 25, 1976

Filed:

May 28, 1974

Appl. No.:

5/473469

Inventors:

Kyung S. Shim - Irvington NY
Edward N. Walsh - New City NY

Assignee:

Stauffer Chemical Company - Westport CT

International Classification:

C07F 908

US Classification:

260928

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. 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.

US Classification:

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 the condensation of these esters with an alkyl ester of a pentavalent phosphorus acid are extracted with an inert organic solvent. 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.
