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: of the disclosure Nitrile copolymers and graft copolymers containing a high proportionate amount of olefinic nitrile are stabilized against thermal color degradation by inclusion into the polymer minor amounts of a compound having the formula: and/or wherein "X" may be oxygen; an imide groups, -NH? or an N-substituted imide group, -NR- wherein "R" may be an alkyl, or a phenyl alkyl group containing from 1 to 8 carbon atoms; "Y" may be an oxygen or a methylene group; and "Z" may be hydrogen or an alkyl group containing from 1 to 8 carbon atoms.

Abstract: This invention relates to a process for polymerizing alpha-olefins in the presence of a Ziegler-type catalyst wherein at least one of dichloroethane, dichloropropane and chlorine gas is added to the process after the polymerization has been initiated. This invention is especially useful when the olefin is propylene and the catalyst is a titanium trichloride complex.
