Abstract: Ethylenically unsaturated monomers are polymerized by an indirect process which electrolytically initiates the polymerization. The indirect electrolytic process utilizes a free initiator and an electron transfer agent in a twophase system comprising (1) a discontinuous organic phase comprised of ethylenically unsaturated monomer(s) and (2) a continuous aqueous phase capable of carrying an electric current.

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: 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: 1360685 Graft polymers STANDARD OIL CO 21 Oct 1971 [13 Nov 1970] 48958/71 Heading C3G A graft polymer is produced by polymerization of (A) from 70 to 85% by weight of an olefinically unsaturated nitrile, (B) 2 to 13% of an alpha-olefin of structure wherein R 1 and R 11 are C 1 to C 7 -alkyl groups, (C) 2 to 30% of a monomer selected from a vinyl ester, acrylate ester, an acrylamide or a methacrylate ester, and (D) up to 17% of a vinyl or vinylidene aromatic monomer, wherein the combined amount of (A)+(B)+(C)+(D) is 100%, in the presence of from 1 to 30 parts by weight per 100 parts of (A) + (B) + (C)+(D) of (E) a rubbery polymer of 50 to 100% by weight of polymerized conjugated diene monomer and 50 to 0% of a polymerized vinyl or vinylidene aromatic monomer. In the examples, graft polymers are prepared in aqueous emulsion from (a) butadiene-styrene rubber or polybutadiene, acrylonitrile, isobutylene, styrene and methyl acrylate, N-t-octyl acrylamide, N-t-butyl acrylamide or vinyl acetate and (b) polybutadiene, acrylonitrile, diisobutylene, styrene and methyl acrylate.
