Abstract: Methods of polymerizing polyethylene-based polymers on a support, and supports coated with polyethylene-based polymers. The coated supports may be used to improve the ink fixation properties of an ink-jet printing medium. The coated supports may also be useful for highly tailored chromatographic separations.

Abstract: Novel methods of forming films on metal or metal alloys are provided. These methods comprise the formation of a metal oxide (e.g., manganese oxide) conversion coating on the metal or metal alloy. The metal-oxide coated metal or metal alloy is then submerged in a mini-emulsion comprising the components (e.g., polymers, oligomers, and/or monomers) to be formed into a film or coating on the metal or metal alloy. The metal ions generated by the metal oxide coating will cause the components to coagulate and deposit on the metal or metal alloy.

Abstract: Medium for chromatographic separations. The medium includes a support with a surface on which interwoven polymers are coated to form a polymer surface. The polymers are covalently linked to the support surface. The polymers are each formed from one or more monomer types and at least one monomer type has an amine functional group. The medium also includes an active molecule immobilized on the polymer surface that is selected to separate reagent materials by chemical structure.

Abstract: Corrosion resistance of metallic components such as stainless steel components of vehicles, and especially aluminum-based components of aircraft, is enhanced by application of an e-coat paint or primer which is enhanced by incorporation of cerium ions into the e-coat electrolytic bath. The resulting overall coating includes a cerium-based layer under a cerium-enhanced e-coat paint or primer layer.

Abstract: A cerium-based coating for corrosion resistance is applied by exposing a cleaned aluminum-based component to a corrosion-inhibiting cerium solution containing cerium ions in the presence of an oxidizing agent. The coating deposits spontaneously without an external source of electrons.

Abstract: Primer coating compositions containing rare earth compounds having good adhesion to metals, including aluminum and aluminum alloys, are provided herewith. Also disclosed are processes for preparing said coating compositions, methods of using same, as well as substrates coated with the coating compositions.

Abstract: The corrosion resistance of an aluminum or aluminum alloy component is enhanced by immersing an aluminum alloy to act as a cathode and an oxygen-evolving anode in an electrolyte comprising water, cerium ions, and an additive selected from among animal gelatin, derivatives of animal gelatin, and amino acids, then passing an electrical current through the electrolyte to deposit a cerium-based coating onto the aluminum-based component.

Abstract: Polymerization of ethylenically unsaturated monomers such as methyl methacrylate can be initiated in solutions containing monomer and a special non-polymeric initiator with intense ultrasound. The number average molecular weight of the poly(methyl methacrylate) that forms is about 300,000 gmol.sup.-1 as compared with polystyrene standards. The conversion of the polymerization is about 50% for poly(methyl methacrylate). Variations of the polymerization rate with time and the amount of the initiator are explained by a simple reaction mechanism.

Abstract: A transparent composite material, which may take the form of a plate, includes a polymeric matrix and glass fibers embedded within the matrix. The polymer of the matrix and the glass of the fibers are transparent and have substantially the same index of refraction. A bond exists between the glass of the fibers and the polymer of the matrix. The composite may be formed by immersing the fibers in a monomer and then curing the monomer to a polymer.

Abstract: A process is provided for making alkylalkoxysilane by reacting a C.sub.1 -C.sub.5 alkyl alcohol in the presence of an effective catalytic amount of copper metal and an alkali metal carboxylate catalyst.
