US Patent:

41104153, Aug 29, 1978

Filed:

Dec 29, 1975

Appl. No.:

5/645133

Inventors:

Eugene J. Boros - South Charleston WV
Anthony J. Papa - Saint Albans WV

Assignee:

Union Carbide Corporation - New York NY

International Classification:

C07F 940
C08J 900

US Classification:

260953

Abstract:

Novel polymethylol polyphosphonates are prepared by reacting a trisubstituted polyphosphite having at least one alkyl group and formaldehyde. The phosphite reactant may contain the requisite hydroxyl functionality [e. g. - heptakis (dipropylene glycol) triphosphite] or the hydroxyl functionality may be introduced by carrying out the reaction in the presence of a polyol, e. g. - glycerol, as a protic solvent. The resulting reaction product is a water-soluble liquid of relatively low viscosity and may be employed without any refining. The thus-formed polyphosphonates can be readily incorporated into either rigid urethane foam formulations to impart flame retardancy or phenolic resins to improve flexibility.

David W. Peck - Charleston WV

Assignee:

Union Carbide Corporation - New York NY

International Classification:

C07L125067

US Classification:

560134

Abstract:

Process for producing a 1-naphthyl carbamate by reacting 1-naphthyl with methyl isocyanate utilizing an anion exchange resin catalyst treated to convert weak-base groups to their catalytically active free amine form while maintaining any strong-base groups in their catalytically inactive salt form.

Assignee:

Union Carbide Corporation - New York NY

International Classification:

L08D 520

US Classification:

521 28
