    Abstract: A process for inhibiting chemical reactions of a fluid functionally reactive organic material by mixing it with supercritical fluid ("SCF") or near supercritical fluid, especially carbon dioxide maintained under supercritical fluid conditions. The process includes the ability to restrain a chemical reaction that occurs otherwise between functionally compatible organic molecules by the inclusion of supercritical fluid, particularly CO2, with the molecules, so that the reaction can be made to occur according to a predetermined but different from normal pattern.

    Abstract: A process is provided for the preparation of a mixture of parylene dimers wherein the distribution of dimers within the mixture is predetermined by the proper selection of halogenated and non-halogenated 2,2-paracyclophane starting material. Since the dimers are free of alpha-halogens, the formation of environmentally undesirable acid halides during the deposition of parylene films and coatings is avoided. Since the dimers are useful in the preparation of inert, transparent, conformal coatings of parylene, desirable chemical and/or physical properties can be imparted to such coating by formation of a dimer mixture of a predetermined composition. The parylene film properties, composition and deposition conditions will be different by varying dimer distribution.

    Abstract: This invention is directed to improved spraying apparatus for coating substrates with a coating material and supercritical fluid which apparatus is provided with various features, either alone or in combination, to prevent undesirable premature cooling of the coating mixture which might detrimentally affect the final coating on the substrate; to prevent undesirable depressurization of supercritical fluid contained in the coating mixture which remains in the spray gun after spraying has been stopped; and/or to desirably provide the ability to mix the components of the coating mixture directly in the spray gun. Methods for utilizing these features in the spraying apparatus of the present invention are also disclosed.
