Abstract: A method of radically (co)polymerizing vinyl ester, vinyl halide, diene, acrylonitrile and .alpha.-olefin monomers, optionally with one or more ethylenically unsaturated monomers, with a polymerization initiator in the presence of an amount of at least one peroxyacid chain transfer agent effective to reduce the molecular weight of the (co)polymer in comparison to a (co)polymer made by the same process without chain transfer agent, is disclosed. Also disclosed are (co)polymers produced by the method and the use of particular peroxyacids as chain transfer agents in the radical polymerization of one or more ethylenically unsaturated monomers.

Abstract: The invention relates to polyketone yarns of which the maximum tangential modulus at an elongation of more than 0.2% is at least 10 N/tex which display both high strength and, if so desired, a high elongation at break. The quality number, which is measured on a single filament out of a bundle of at least about 30 filaments spun simultaneously through one spinneret and given as .sigma., .epsilon., is higher than 85 mN/tex, preferably higher than 100 mN/tex. The quality number of a yarn spun through one spinneret of one or more holes is higher than 110 mN/tex, preferably higher than 120 mN/tex. The yarns are manufactured by extruding a solution of a linear polymer of alternating ethylene and carbon monoxide units in a resorcinol-containing solvent, after which the solvent is removed with the aid of methanol as coagulant.
