53553, 53428

Abstract:

One aspect of the invention pertains to a device for mixing and dispensing fluids, which generally includes a housing; a mixing chamber having a first inlet for introducing a first fluid into the mixing chamber, a second inlet for introducing a second fluid into the mixing chamber, and an outlet through which fluid may exit the mixing chamber; and a valving rod received within the mixing chamber and movable between an open position, in which the first and second inlets are in fluid communication with the mixing chamber, a cleaning position, in which the valving rod substantially seals closed the first inlet but does not seal closed the second inlet, and a closed position, in which the valving rod substantially seals closed the first and second inlets.

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.

Assignee:

Union Carbide Corporation - New York NY

International Classification:

C08G 1814

US Classification:

260 25AC

Abstract:

Cellular urethane polymers are provided by effecting the reaction of an organic polyol reactant comprising a polyether polyol and an organic polyisocyanate reactant in the presence of a blowing agent and a catalyst system comprising an N,N-dimethylaminoalkoxypropionitrile. The said N,N-dimethylaminoalkoxypropionitriles are versatile, low odor catalysts and are useful in forming cellular urethane polymers ranging from all water-blown flexible polyether foam to all fluorocarbon-blown rigid foam products. Especially preferred for use in the practice of the invention are 3-(2-dimethylaminoethoxy)propionitrile and 3-[2-(2-dimethylaminoethoxy)ethoxy]propionitrile either as such or in combination with other catalysts including other tertiary-amine components and/or organic compounds of tin. Also provided are blended catalyst systems comprising said dimethylaminoalkoxypropionitriles.

International Classification:

C08G 1848

US Classification:

527174

Abstract:

A polyol blend is disclosed for making polyurethane foams. The blend includes a first polyol having a functionality of about 2, a hydroxyl number ranging from about 20 to about 90, and an equivalent weight ranging from about 600 to about 2800; a second polyol having a functionality ranging from about 4 to about 8, a hydroxyl number ranging from about 200 to about 600, and an equivalent weight ranging from about 90 to about 280; and a third polyol having a functionality ranging from about 2. 5 to about 4, a hydroxyl number ranging from about 15 to about 500, and an equivalent weight ranging from about 180 to about 4000. The polyol blend is capable of reacting with an isocyanate compound in the presence of water to produce a foam having a density ranging from about 0. 5 to about 5 pounds/ft. sup. 3, a compressive strength ranging from about 3 to about 20 psi, and an airflow ranging from about 10 to about 1000 cc/minute.

Abstract:

Cellular urethane polymers are provided by effecting the reaction of an organic polyol reactant comprising a polyether polyol and an organic polyisocyanate reactant in the presence of a blowing agent and a catalyst system comprising a tertiary-dimethylamino ether mono-ol. In the dimethylamino ether mono-ols employed as catalysts in the practice of the invention, the tertiary-dimethylamino group and the hydroxyl group are positioned beta to a common acyclic ether oxygen atom or to different acyclic ether oxygen atoms which in turn are positioned beta to one another. The said dimethylamino ether mono-ols are versatile, low odor catalysts and are useful in forming cellular urethane polymers ranging from all water-blown flexible polyether foam to all fluorocarbon-blown rigid foam including semi-flexible and high-resilience foam products. Especially preferred for use in the practice of the invention are 2-(2-dimethylaminoethoxy)ethanol and 2-[2-(2-dimethylaminoethoxy)ethoxy]ethanol either as such or in combination with other catalysts including other tertiary-amine components and/or organic compounds of tin. Also provided are blended catalyst systems comprising said dimethylamino ether mono-ols.

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.
