    Abstract: The present invention relates to fibers produced by melt spinning of high nitrile multipolymers. The fibers are prepared in a solventless, waterless, melt spinning process. The melt spun high nitrile fiber is made from a high nitrile melt processable multipolymer comprising about 50% to about 95% by weight polymerized acrylonitrile monomer and 5% to about 50% by weight of a polymerized olefinically unsaturated monomer. A process for the production of the fibers is disclosed which comprises (a) melt extruding a high nitrile multipolymer in the absence of a solvent and in the absence of water and (b) spinning the high nitrile polymer melt into a high nitrile filament at a temperature higher than the glass transition temperature of the multipolymer and (c) collecting the monofilament or the multiple filament as a fiber bundle.

    Abstract: A process for the production of high nitrile fibres comprising 50-95% by weight polymerised acrylonitrile monomer and 5-50% by weight of at least one polymerised olefinically unsaturated monomer is disclosed, in which the high nitrile multipolymer is melt extruded in the absence of solvent and water, and the resultant melt spun into a high nitrile filament at a temperature higher than the glass transition temperature of the multipolymer, with the monofilament or multiple filaments being collected as a bundle, web or combinations thereof.

    Abstract: CATALYSTS USEFUL FOR PREPARING POLYAMIDES A polyamide is produced by polymerizing at least one of an alpha, beta unsaturated carboxylic acid and ammonia, an ammonium salt of an alpha, beta unsaturated carboxylic acid, an alpha, beta unsaturated nitrite and water, a beta-amino propionic acid or alkyl derivative thereof and an alpha, beta unsaturated amide and ammoniua in the presence of a catalyst comprising a pentaammine cobalt (III) complex.
