Abstract: Compositions are provided including a free-radically reactive component, a photoradical generator, and either a crosslinker having a photodegradable linkage or a chemical blowing agent, an epoxy component, and a photoacid generator. Polymeric films including reaction products of the compositions are also provided. A debondable article including a polymeric film containing a crosslinker having a photodegradable linkage is further provided, as well as a method of debonding the article. Foam compositions are also provided, including foamed matrices including the reaction products of the compositions. Further, articles and foam adhesives are provided including a substrate and a composition or foam composition disposed on the substrate.

Abstract: A metalworking composition in the form of a stable emulsion having lubricating as well as cleaning properties which is based essentially on non-hazardous components. The composition comprises a homogenous mixture of water, a vegetable oil, a phosphatide, a thickening agent and an emulsifying system consisting of an anionic surfactant and a nonionic biodegradable detergent. The emulsion-type mixture can be prepared through sequential addition of the non-hazardous components followed by homogenization in a high-speed mixture. A concentrated lubricant is thereby obtained which readily forms an adhering film on the surface of a metallic workpiece and all types of metalworking mediums during machining operations to effectively prevent galling or fouling. The metalworking composition is environmentally safe and significantly reduces problems associated with cleanup and corrosion.

Abstract: The continuous stationery carrier which is adapted to be fed through computer printers, word processing printers, and the like so as to permit the stationery carried therein to be printed upon comprises a plurality of polyethylene backing sheets sequentially joined together along perforated fold lines and equipped with a plurality of feed apertures along the right and left margins thereof. Each backing sheet has a polyethylene cover sheet joined thereto in pocket forming relationship therewith so as to be capable of retaining a piece of stationery. Each cover sheet is provided with at least one aperture therein through which the stationery may be printed upon. The shape and the size of the cover sheets and the apertures therein may be selected to suit a particular application.
