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: (5036) IMPACT-RESISTANT, HIGH SOFTENING MALEIC ANHYDRIDE COPOLYMERS High softening polymeric compositions having good impact resistance are composed of polymerized maleic anhydride, an alpha-olefin such as diisobutylene, styrene and a preformed diene rubber such as a styrene-butadiene rubber.
