    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: 1352437 Graft polymers STANDARD OIL CO 24 June 1971 [22 Sept 1970] 29631/71 Heading C3G A resinous polymer is produced by polymerization of 100 parts by weight of (A) an olefinically unsaturated nitrile of structure wherein R represents hydrogen, a C 1 to C 4 -alkyl group or a halogen, (B) 0À5 to 10 moles per mole of (A) of a vinyl or vinylidene aromatic monomer and (C) 0À2 to 2À5 moles per mole of (A) of maleimide in the presence of from 1 to 20 parts of a conjugated diolefin elastomer. Examples are given in which styrene, acrylonitrile and maleimide are polymerized in an aqueous emulsion containing polybutadiene or butadienestyrene copolymer.
