US Patent:

40382109, Jul 26, 1977

Filed:

Jul 17, 1975

Appl. No.:

5/596628

Inventors:

Walter Richard Rosemund - Englewood NJ
Michael Ray Sandner - Charleston WV
David John Trecker - South Charleston WV

Assignee:

Union Carbide Corporation - New York NY

International Classification:

B01J 3102

US Classification:

252426

Abstract:

Cellular urethane polymers essentially free of the strong, objectionable amine odor characteristic of N-ethylmorpholine, are provided by effecting the polyurethane forming reaction in the presence of beta-tertamino nitriles. In view of their low residual odor and effectiveness in the catalysis of the water-isocyanate reaction, the beta-amino nitriles either alone or in combination with other tertiary amines, are used with particular advantage as direct replacements for N-ethylmorpholine in the manufacture of water-blown flexible polyurethanes, both molded and free-rise, including high-resilience foam as well as foams stabilized with either organosilicone or silicon-free organic surfactants. Especially effective for the formation of flexible polyester foam stabilized with either type of surfactant are blends of the beta-amino nitrile catalyst such as, in particular, 3-(N,N-dimethylamino)propionitrile, with dimethylethanolamine or a bis[2-(N,N-dimethylamino)alkyl]-ether.

Appl. No.:

5/656383

Walter Richard Rosemund - Englewood NJ
Charles Vincent Rose - Brewster NY

Assignee:

Union Carbide Corporation - New York NY

International Classification:

B32B 518

US Classification:

156 78

Abstract:

One-shot, flexible polyurethane foams capable of being thermally bonded to various substrates are produced by adding low molecular weight alkylene glycols, glycol ethers, triols, alkanolamine, or polyhydric phenols as modifiers to conventional polyisocyanate foaming mixtures.

International Classification:

C08G 1814
C08G 1828

US Classification:

260 25AM

Abstract:

Improved diecuttable polyester urethane foams are provided by the inclusion in the foam formulation of specified minor amounts of certain low molecular weight polyols, typically having hydroxyl numbers of 100 or greater. Representative useful species of such polyols include aliphatic alcohols, such as glycerol and erythritol, polymethylols such as trimethylolpropane, alkanolamines such as triethanolamine and relatively low molecular weight alkylene oxide adducts such as propylene - glycerol adducts and the like. Especially effective diecuttable foam formulations are provided by further employing, as co-additives, certain alkylene oxide adducts of linear alcohols or phenols, sulfonated petroleum oils, ammonium salts and silicone-containing copolymers. If desired, the viscosity and compatibility characteristics of the additive and/or additive and co-additive mixture may be modified by the incorporation of a diluent.
