Patent number: 4038210Abstract: 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.Type: GrantFiled: July 17, 1975Date of Patent: July 26, 1977Assignee: Union Carbide CorporationInventors: Walter Richard Rosemund, Michael Ray Sandner, David John Trecker

Patent number: 4016059Abstract: Compositions of amine derivatives of acrylated epoxidized soybean oil, which are the reaction products of an organic amine with the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, and an acrylyl compound which are useful as coatings and inks are cured by radiation. The compositions can also contain photosensitizers and/or pigments.Type: GrantFiled: March 28, 1975Date of Patent: April 5, 1977Assignee: Union Carbide CorporationInventors: David John Trecker, George Wayne Borden, Oliver Wendell Smith

Patent number: 4012445Abstract: Provided as catalysts for the formation of cellular urethane polymers ranging from flexible to rigid foams, are beta-amino carbonyl compounds wherein carbonyl is present as an amido or carboxylic acid ester group and the beta-amino group is present as dialkylamino or an N-morpholino or N,N'-piperazino heterocyclic nucleus. Effective in the catalysis of the water-isocyanate reaction, these beta-amino amides and beta-amino esters are used with particular advantage in the manufacture of water-blown flexible foams, both molded and free-rise, including high-resilience and flame-retarded foam. The beta-amino carbonyl catalysts allow for the formation of foam products essentially free of the odor associated with amines such as N-ethylmorpholine. In view of this highly desirable characteristic and their other beneficial properties, the catalysts of the invention are advantageously employed as direct replacements for N-ethylmorpholine in high-resilience and other foam formulations.Type: GrantFiled: February 23, 1976Date of Patent: March 15, 1977Assignee: Union Carbide CorporationInventors: David Charles Priest, Michael Ray Sandner, David John Trecker

Patent number: 4003868Abstract: Liquid ink or coating compositions that can be cured by thermal treatment or by a combination of ionizing or non-ionizing radiation and a thermal treatment are disclosed. The components are all essentially non-volatile during cure and the compositions have high viscosities making them eminently suitable for printing applications.Type: GrantFiled: April 25, 1975Date of Patent: January 18, 1977Assignee: Union Carbide CorporationInventors: Oliver Wendell Smith, Charles Hobert Carder, David John Trecker
-
Patent number: 3979270Abstract: The amine derivatives of acrylated epoxidized soybean oil, which is the reaction product of epoxidized soybean oil with acrylic acid or methacrylic acid, are produced by the reaction of acrylated epoxidized soybean oil with an organic amine and cured by radiation. They are useful alone, or in conjunction with a photosensitizer, and/or a pigment as inks and coatings.Type: GrantFiled: March 28, 1975Date of Patent: September 7, 1976Assignee: Union Carbide CorporationInventors: David John Trecker, George Wayne Borden, Oliver Wendell Smith
