    Abstract: A fluorine-containing polymer prepared from at least a spacer group selected from the group consisting of ethylene, alpha-olefins, 1,1′-disubstituted olefins, vinyl alcohols, vinyl ethers, and 1,3-dienes; and a norbornyl radical containing a functional group containing the structure: —C(Rf)(Rf′)Orb wherein Rf and Rf′ are the same or different fluoroalkyl groups of from 1 to about 10 carbon atoms or taken together are (CF2)n wherein n is an integer ranging from 2 to about 10 and Rb is a hydrogen atom or an acid- or base-labile protecting group; r is an integer ranging from 0-4. The fluorine-containing polymer has an absorption coefficient of less than 4.0 mm−1 at a wavelength of 157 nm. These polymers are useful in photoresist compositions for microlithography. They exhibit high transparency at this short wavelength and also possess other key properties, including good plasma etch resistance and adhesive properties.

    Abstract: Certain olefins such as ethylene, .alpha.-olefins and cyclopentene can be polymerized by using catalyst system containing a nickel or palladium .alpha.-diimine complex, a metal containing hydrocarbylation compound, and a selected Lewis acid, or a catalyst system containing certain nickel �II! or palladium �II! compounds, an .alpha.-diimine, a metal containing hydrocarbylation compound, and optionally a selected Lewis acid. The process advantageously produces polyolefins useful for molding resins, films, elastomers and other uses.

    Abstract: This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has a formula according to; R1aR2bR3cSn[CH(OX)R4]d, wherein R1, R2, and R3 are the same or different and represent an optionally substituted hydrocarbyl, aromatic, alkoxide, amide, halide or stannyl group, R4 represents an optionally substituted hydrocarbyl or optionally substituted aryl group. a, b, and c are independently 0, 1, 2, or 3; d is 1, 2 or 3; and a+b+c+d=4; and X is an acid-labile or moisture-labile protecting group. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.
