Abstract: A polymerizable acrylate or epoxy composition includes a dye comprised of a conjugated system containing a chromophore that is subject to effective decoupling, by a reactive alkylating species generated by the polymerization initiator, to produce a permanent loss of color and thereby to indicate that curing has occurred.

Abstract: Certain pyridine and quinoline derivatives' which inhibit replication of the retroviruses HIV-1, HIV-2 and human cytomegalovirus (HCMV) are provided. Pharmaceutical compositions useful in methods of treating or inhibiting certain retrovirus infections are described.

Abstract: The use of a phosphine oxide photoinitiator enables the effective curing of a polymerizable acrylate formulation despite the incorporation of a high concentration of a fluorescing agent, thereby facilitating, and enhancing the efficiency of, evaluation of the cured deposit utilizing its fluorescent response.

Abstract: The adhesive formulation minimizes corrosion of copper surfaces (e.g., of motor commutators) caused by volatile ingredients of conventional acrylate compositions, and cure speeds are significantly increased thereover.

Abstract: The polymerizable acrylate formulation, and method utilizing the same, employ a catalyst system that includes a tertiary aromatic amine compound and an air-curing polyether-ene polymer, in a specified ratio, in combination with an acid ingredient and a transition metal that together form a coordination compound. The formulation cures through bulk, as well as on the surface, in a highly effective manner.

Abstract: An acrylate composition, especially useful for producing conformal coatings on circuit board assemblies, includes a photoinitiator and an air-curing system, the latter being comprised of a compound having multiple allyloxy groups in its molecule and a transition metal salt catalyst. The composition is highly stable against auto-induced reaction in the absence of oxygen and at room temperature; it contains no active oxygen catalyst and no nonreactive diluent, and is advantageously formulated as a one-part product.

Abstract: An acrylate encapsulation formulation reacts at a high rate of speed, when exposed to radiation inclusive of wavelengths in the ultraviolet and the visible range, to initially produce a relatively thick skin and to ultimately cure to a relatively low-stress deposit having good physical definition and surface properties. The method entails exposure of the formulation, on an object, to radiation for initialing photopolymerization and thermal polymerization, and the apparatus includes closely juxtaposed actinic radiation and thermal energy sources.

Abstract: A multi-part composition is provided which is suitable for use as an adhesive, a potting compound, a coating or a sealant. It consists of a polymerizable acrylate formulation and an activating formulation, the latter usually comprising an amine-aldehyde condensation product diluted with a liquid vinyl ether; liquid epoxides may also be included as diluents in the activating formulation.

Abstract: An adhesive package comprising a first component including an EPDM polymer and p-quinone dioxime, a second component including an EPDM polymer and an inorganic peroxide, said first and second components separated by a film of 1,2-syndiotactic polybutadiene is disclosed. A process is also set forth for sealing EPDM sheet comprising disposing an adhesive melt, said melt comprising EPDM, p-quinone dioxime, an inorganic peroxide and 1,2-syndiotactic polybutadiene, upon a first EPDM sheet and overlapping the sheet, on which the adhesive has been disposed, with another EPDM sheet to be sealed to the first sheet.

Abstract: Antioxidants containing a sulfonyl azide moiety react with polymers having carbon-hydrogen bonds thereby becoming non-extractable and non-migratory.

Abstract: Halogenated olefin copolymer rubber, particularly halogenated EPDM (prepared by heating the rubber in admixture with an N-haloamide [e.g., 1,3-dichloro-5,5-dimethyl hydantoin or N,N'-dichloro-p-toluene sulfonamide]) is blended with curatives (sulfur, accelerator) and a resorcinol-aldehyde condensation product in which the aldehyde has 2-4 carbon atoms (e.g., acetaldehyde) to make a vulcanizable adhesive for nylon textile. Nylon fabric coated with the composition is useful for making air bags (passive restraints for automotive vehicles). The adhesive is also useful for making nylon-reinforced tires, hose, etc.
