    摘要: Methods and compositions relate to a Fischer-Tropsch catalyst utilized to convert syngas into paraffins. The catalyst includes a given amount of sulfur content from contact of a catalytic supported metal with sulfur. Subsequent activation of the catalyst prepares the catalyst to be used for conversion of the syngas. The sulfur content maintained in the catalyst after being activated influences selectivity to paraffins over olefins and oxygenates.

    摘要: A wet-etch composition for polyamic acids and partially cured polyamic acids comprising an aqueous solution having a major portion of water, a substituted hydrocarbon solvent and a non-ionic base that is strong enough to deprotonate the polyamic acid or a partially cured polyamic acid in a weight ratio of 0.1-49:49-0.1, with the proviso that the composition contains less than 1.0 percent ionic base. The present invention further provides a process for wet-etching polyamic acids or partially cured polyamic acids.

    摘要: Resinous condensation polymers of polycarboxylic acid compounds and aromatic diprimary amines comprising diamino-t-butyltoluene are described. In particular, film-forming polyamides, polyimides and polyamide-imides and their copolymers made using diamino-t-butyltoluene which have amino groups meta or para to each other on a benzene ring are described. These polymers have some solubility in organic solvents such as N-methylpyrrolidone, a high glass transition temperature, excellent thermal stability, and are useful in films, fibers and composites, and in the electronics industry as electrical component substrates, protective coatings, interlevel dielectrics and the like.

    摘要: Partially soluble, film-forming polyimides and their copolymers made using 3,5-diaminobenzotrifluoride are described. Thin films and coatings of these materials are relatively colorless and the polymers have a high Tg, excellent thermal stability, lower moisture uptake, and lower dielectric constant. They are useful as films, fibers, molded articles and as protective coatings, interlevel dielectrics, electric circuit substrates and the like for the electronics industry.
