Abstract: Title: A PROCESS FOR MAKING A POLYMER OF ACRYLONI TRILE, METHACRYLONITRILE AND OLEFINICALLY UNSATURATED MONOMERS A process for making a thermally stable melt processable acrylonitrile/methacrylonitrile/olefinically unsaturated multipolymer, comprising polymerizing a mixture of acrylonitrile monomer, methacrylonitrile monomer, and olefinically unsaturated monomer in which the rate of addition of the multimonomer mixture isset by the rate of polymerization so that the concentration of unreacted acrylonitrile monomer, unreacted methacrylonitrile monomer and unreacted olefinically unsaturated monomer is low and the polymerization process is in a monomer starved condition.

Abstract: A homogeneous, high nitrile melt processable acrylonitrile olefinically unsaturated multipolymer and a process for making the multipolymer, comprising polymerizing a mixture of acrylonitrile monomer and one or more olefinically unsaturated monomers, in which the rate of addition of the multimonomer mixture is set by the rate of polymerization so that the concentration of unreacted acrylonitrile monomers and unreacted olefinically unsaturated monomer(s) is low and the polymerization process is in a monomer starved condition.

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: Light colored, high molecular weight thermoplastic xylene-formaldehyde polymers are prepared by reaction of substantially equimolar amounts of xylene and formaldehyde in the presence of a strong acid catalyst by the exclusion of air from the reactor.
