US Patent:

47972408, Jan 10, 1989

Filed:

Jun 8, 1987

Appl. No.:

7/058963

Inventors:

Gary D. Andrew - Walnutport PA
Edward A. Galla - Macungie PA
Robert L. Ricci - Allentown PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

C08G 1814

US Classification:

264 464

Abstract:

To prevent the staining of a nitrocellulose coated shoe upper by a polyurethane shoe sole prepared from a mixture comprising a polyisocyanate, a polyol, a chain extender, a tertiary amine catalyst, a surfactant and water, an effective amount of a reactive organic halogen compound, preferably a halogenated fire retardant, is added.

Appl. No.:

7/226330

Inventors:

Edward A. Galla - Macungie PA
Robert L. Ricci - Allentown PA
Gary D. Andrew - Walnutport PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

C04G 1914
B01J 3100

US Classification:

502164

Abstract:

A method for preparing polyurethane product by the reaction of an organic polyisocyanate with a polyester or polyether polyol in the presence of a catalytically effective amount of a catalyst system consisting essentially of a tertiary amine and 1 to 35 wt %, based on the tertiary amine, of an N-hydroxyalkyl quaternary ammonium carbonylate salt, particularly a quaternary triethylenediamine compound. The preferred quaternary composition is the reaction product of an alkylene oxide in excess of equimolar amount with triethylenediamine in the presence of an acid. The use of such catalyst system advantageously improves the cure time of the urethane reaction, when compared to a system containing solely a tertiary amine, while maintaining the same initiation of the reaction. This advantage can be transferred to a delay in the initiation time while maintaining or shortening the cure time by adjustments in the total amount of the catalyst system used.

Appl. No.:

6/580317

Inventors:

Edward A. Galla - Whitehall PA
Bruce A. Smoyer - Allentown PA

Assignee:

Air Products and Chemicals, Inc. - Allentown PA

International Classification:

B29D 2700

US Classification:

264 54

Abstract:

A method for shipping flexible polyurethane foam product comprising (a) reacting a flexible polyurethane foam composition containing a polyisocyanate, a polyether polyol, a surfactant, a catalyst and water to provide a foam product, (b) conditioning the foam product to develop substantially full cure, (c) applying a force to compress the product to a fraction of its original size, (d) shipping the compressed product and (e) removing the compression force so that the product may return to its original size, the improvement for reducing the conditioning time or temperature prior to compressing the foam product while ensuring the substantial restitution of the foamed product when the compression force is removed which improvement comprises employing as the catalyst in the flexible polyurethane foam composition a polyurethane catalyst which is N-alkyl morpholine or N-(dialkylaminoalky) morpholine.
