Abstract: Compositions comprising at least one adduct of perhalogenated cyclic conjugated dienes and olefinically-unsaturated dienophiles having a vinyl content in excess of 50 percent have been found to be unexpectedly effective adhesive systems for bonding a variety of elastomeric materials, including vulcanizable and vulcanized natural and synthetic elastomer compositions, to themselves and other structural substrates.

Abstract: A method for preparing a monoclonal antibody of improved cross-species specificity. The method includes the steps of preparing an inoculum antigen from a first species of animal producing the antigen and then immunizing a selected subject animal with the inoculum antigen. The method further includes the steps of fusing spleen cells from the immunized subject animal with myeloma cells to produce hybridomas. A test antigen is prepared corresponding to the inoculum antigen but derived from a second species of animal, distinct from the first species of animal from which the inoculum antigen was prepared. Hybridomas are screened for desired antibody production against the test antigen. The hybridoma producing antibodies most active against the test antigen is then cultured, and monoclonal antibodies are produced therefrom.

Abstract: Adhesion of silicone elastomers to metal substrates, especially zinc phosphatized metal substrates, is significantly improved by exposing the substrate to a plasma comprising at least one organosilicon compound. In a preferred embodiment, the plasma-treated substrates are soaked in gaseous organosilicon monomer compound.

Abstract: Adhesion of silicone elastomers to metal substrates, especially zinc phosphatized metal substrates, is significantly improved by exposing the substrate to a glow discharge plasma selected from the group consisting of at least one inert gas, at least one organosilicon compound or a combination thereof, prior to the application of any adhesive materials to such substrates.

Abstract: Organotin semiconductor thin films are deposited on a substrate by plasma deposition of reactive organotin species. Conductivity can be increased by heat-treating organotin semiconductors in a reducing atmosphere at a temperature below the melting point of tin. Organotin semiconductors are rendered conductive by exposure to electron or particle beam.

Abstract: The surfaces of organic and inorganic substrates, such as polyethylene film and metals, respectively, can be modified by cold plasma deposition of difluorocarbene or trifluoromethyl radical specie generated by subjecting precursor vapor, for example, perfluorocyclobutane or hexafluoroethane, to a radio frequency electrical glow discharge.
