摘要： Methods and apparatus for vulcanizing rubber and like material (10). Ultrasonic energy at about 10 to 100 kilohertz is applied to the material (10) at an energy intensity sufficient to generate heat to a temperature in the range of about 200 to 300 degrees Fahrenheit, while a static pressure is applied on the material (10) sufficient to prevent substantial cavitation and material degradation. The application of the ultrasonic energy and the pressure is maintained for at least about 10 minutes for each 1/8 inch in thickness of the material (10).

摘要： Methods are disclosed for the metallizing of non-metallic substrates, i.e. polymeric substrates, by the coating of the substrate with polymerizable monomers in the presence of a small amount of silver ion. The substrate is cleaned, acid etched and then contacted with a monomer solution containing a soluble silver salt. The monomers are preferably polyfunctional and form a polymerized layer grafted onto the polymer substrate. A peroxide is also disclosed in the monomer solution for regeneration of the silver ion concentration and to combine with monomers to produce homopolymers which also attach to the active sites on the substrate and to side chains of the graft polymer. The grafted layer contains silver atoms closely bound to it and the silver atoms form nucleating agents for the deposition of copper from an electroless plating bath. The metallized substrate may then be further electroplated.

摘要： The present invention is an improved wallboard joint compound comprising an inorganic joint compound such as, for example, gypsum, mixed with water, plus one or more additives selected to reduce the moisture in the gypsum compound and improve the strength of the finished wallboard joint. The first additive is selected from a class of water soluble functional polymer with either nitrogen or sulfonate, such as, for example, polyvinyl pyrrolidone (PVP). A second additive is selected from a class of solid epoxy resins, preferably added together with the first additive. These two additives, when mixed with the joint compound alone or in combination, produced a more flexible, higher strength wallboard with a reduce moisture content and quicker drying time.

摘要： A method is disclosed for protecting aluminum and aluminum alloys by the chemical bonding of a polymerized coating to the aluminum oxide on the aluminum surface. The protective coating is graft polymerized from a solution onto the aluminum in the presence of a small amount of silver ion as an initiator. A peroxide is present during the graft polymerization to regenerate silver ions and to catalyze polymerization of monomers and prepolymers which attach to the aluminum surface. The monomers are vinyl monomers containing one or more hydroxy, carboxy, glycidyl and aziridinyl groups. The prepolymers are polyurethane resins and aliphatic, cycloaliphatic and aromatic epoxy resins. The vinyl monomers and prepolymers are cross-linked to provide a transparent, impervious protective coating on the aluminum. The coated aluminum article made by the above method is also disclosed.

摘要： Broadly, the present invention is directed to an adhesive composition which comprises an epoxy resin, an effective amount of a mercapto curing agent or curative for said epoxy resin, and a compatibilizing amount of a polysulfide compound which has a performance improving fraction of its --SH groups rendered unreactive with the epoxy groups in said composition. Optionally, the adhesive composition can contain amine or amide curing agents in addition to the mercapto curative. Advantageously, at least about 5% of the number of reactive thiol groups of the polysulfide compound are rendered unreactive, advantageously at least about 25%, and preferably at least about 50%. Preferred polysulfide compatibilizing compounds are adducts of a polysulfide and a component which contains functionality reactive with a thiol group, but which contains no residual functionality reactive with epoxy groups in the composition once the polysulfide adduct is formed. Another aspect of the present invention is a method for improving the performance of an adhesive composition of an epoxy resin and a mercapto curative, which method comprises incorporating a compatibilizing amount of polysulfide compound which has had a performance improving fraction of its --SH groups rendered unreactive with epoxy groups in the composition. The polysulfide compatibilizing adduct is formed by the reaction of a polysulfide and a component that contains functionality reactive with thiol groups, but which contains no residual functionality reactive with epoxy groups in the adduct.

摘要： This invention provides a process for so treating tobacco, for use in cigars or cigarettes, as to activate the surface of the tobacco to remove the undesirable components of the smoke as the smoke passes along the cigar or cigarette, before reaching the smoker. The process provides for grafting onto the cellulosic constituents of the tobacco a graft polymer or copolymer having free functional groups reactive with the undesirable component of the tobacco smoke. The cellulosic constituents can be activated by an ionic or free radical process to yield a reactive site on the cellulosic chain which can subsequently be reacted with monomers containing active double bonds, e.g., olefins, vinyl monomers or acrylic monomers as well as polymerizable ring compounds each having the desired active substituents. Preferably, this invention is applicable to treating tobacco so as to provide a graft polymer or copolymer containing acidic groups which can react with the basic, or alkaline, components of tobacco smoke. This invention also provides an activated tobacco comprising graft polymers or copolymers formed on its surface.
