  • Patent number: 4243500
    Abstract: A pressure sensitive adhesive is formed from a composition comprising mono-functional unsaturated acrylate ester monomer, essentially saturated tackifying resin polymer dissolved in the acrylate ester, non-crystallizing elastomeric material also dissolved in the acrylate ester, and an initiator responsive to ultraviolet light or other penetrating radiation such as electron beam, gamma or X-ray radiation. The composition is cured by subjection to ultraviolet light or other radiation, which causes the initiator to induce polymerization of both the acrylate ester and the non-crystallizing elastomeric material, apparently with co-polymerization therebetween.

  • Patent number: 4234476
    Abstract: A specific type of protein, which has been designated B-protein (Bucovaz-protein), is present in most serum of individuals with cancer. The B-protein interacts with a low molecular weight protein component, which is released by the coenzyme A-synthesizing protein complex (CoA-SPC) of Bakers' yeast during the course of CoA synthesis. This low molecular weight protein, for purposes of identification, is referred to as binding protein. The binding protein has a molecular weight of 10,000 to 15,000. Interaction of radioactively labeled binding protein of CoA-SPC with the B-protein of serum provides a marker for the detection of cancer. Of 3005 serums assayed, which included 908 patients diagnosed as having cancer, the B-protein assay agreed with the clinical diagnosis in more than 89% of the cases.

  • Patent number: 4224398
    Abstract: A photopolymerizable system is provided as a latex system that is an oil-in-water polymer emulsion including particulates of water-insoluble polymers in combination with a water-soluble or water-dispersible, light-sensitive polymer having multiple light-sensitive moieties. Prior to coating onto a substrate, the system is a three-phase precursor emulsion of the emulsion particulates, the water phase, and the light-sensitive polymer. After coating, the bulk of the water phase is evaporated off, leaving a two-phase system of the emulsion particulates surrounded by the light-sensitive polymer. When selected areas are subjected to actinic radiation, a water-insoluble matrix is formed, the matrix containing cross-linked light-sensitive polymer having dispersed therethrough and/or included therein the water-soluble polymer particulates, thus forming oleophilic image areas.
