Abstract: Process of making amines by inter alia the (i) intramolecular condensation of an amino compound to an amine having a lower molecular weight or (ii) the intermolecular condensation of an amino compound with one or more of another amino compound or a compound containing an alcoholic hydroxyl group using a Group IVB metal oxide condensation catalyst. The preferred process involves the manufacture of alkyleneamines, most desirably polyalkylenepolyamines, by such condensation reactions utilizing catalysts containing titanium oxide, zirconium oxide or mixtures of them.

Abstract: A new method is provided to impart a hydrophilic lubricious coating onto articles such as medical devices. A device, for example a catheter, is first contacted with a polyisocyanate solution, to provide coupling, then contacted with a poly(carboxylic acid) solution to give a coating, and is then finally oven dried. These coatings have lubricity that only becomes manifest upon exposure to water or body fluids, and moreover, are also long lasting and have good abrasion resistance. This combination of properties is not available from other currently used or proposed coatings such as Teflon.

Abstract: A process which comprises (i) the generation of release surfaces by application to predetermined areas of a solid surface of a solution, suspension or dispersion of a release agent and a supercritical fluid that vaporizes from the release agent, (ii) the deposition of a mass onto the release surface containing the release agent, and (iii) the separation of the mass or a product derived from the mass from such surface covered by the release agent. Novel apparatus for carrying out the process are described.

Abstract: This invention relates to processes for preparing aqueous polymer emulsions useful as thickening agents in aqueous compositions in which plating and/or grit formation is reduced in said processes. This invention also relates to methods for reducing plating and/or grit formation in processes for preparing aqueous polymer emulsions useful as thickening agents in aqueous compositions. This invention further relates to polymers which are soluble in, or swelled by, an aqueous alkaline medium to provide thickeners for use in aqueous coating compositions, especially latex paints.
