Abstract: Cyclopentadiene derivatives, method for preparing cyclopentadiene derivatives, and use of cyclopentadiene derivatives in curable binder compositions.

Abstract: A process for casting metal which includes pouring the metal into or around a molded article obtained from a molding composition wherein the binder includes certain fulvenes and/or prepolymers thereof, and a metal salt catalyst. The metal is cooled, solidified, and separated from the molded article.

Abstract: A binder composition which contains certain fulvenes and/or prepolymers thereof, and a metal salt catalyst.

Abstract: A binder composition which contains certain fulvenes and/or prepolymers thereof, and a metal salt catalyst.

Abstract: Foundry cores and molds for casting metals are prepared by forming a binder comprising a polyol, an isocyanato urethane polymer and a urethane catalyst. The foundry cores and molds of this invention are formed by processes known in the industry as the "cold box" process and the no-bake process. The binder is especially useful for casting non-ferrous metals, for example, the casting of aluminum, magnesium and other lightweight metals. The cores and molds produced for casting aluminum and other lightweight metals exhibit excellent shakeout while retaining other desirable core and mold properties.

Abstract: A foundry binder which contains certain fulvenes and/or prepolymers thereof, and an acid catalyst.

Abstract: An adhesive system for coating polyester cord to effect the bonding of rubber thereto in preparing vulcanized reinforced structures, especially pneumatic tires, which system consists of a first heat-cured coating of an admixture of a polyepoxide and a linear carbon-to-carbon addition polymer containing pendent aminimide and N-pyrrolidonyl groups and a second heat-cured coating of a RFL composition.

Abstract: An adhesive system for coating a filamentary substrate, specifically polyester filamentary elements, to effect the bonding of rubber thereto in preparing vulcanized reinforced structures, especially pneumatic tires, which system consists of a first coating of the in situ reaction product of a polyepoxide and a quaternized copolymer of 4-vinylpyridine and an aminimide and a second heat-cured coating of a RFL composition.

Abstract: Unsymmetrical dimethyl hydrazine is prepared by a process wherein aqueous 1,1-dimethylurea is initially reacted with a hypochlorite salt whereupon the resultant intermediate essentially in form of a N-chloro derivative of said urea is rearranged in accordance with the Hofmann reaction to yield the desired substituted hydrazine.

Abstract: An adhesive system for coating a filamentary substrate, specifically steel wire, to effect the bonding of rubber thereto in preparing vulcanized reinforced structures, especially pneumatic tires, which system consists of a first heat-cured coating of a linear carbon-to-carbon addition polymer having pendent aminimide and c-pyridyl groups and a second heat-cured coating of a RFL composition.
