Abstract: The color and impact strength of nitrile polymers, prepared by polymn. of an olefinically unsatd. nitrile with a monovinyl monomer in the presence of a rubber, were improved by heating the polymer to a plastic state in the absence of O and in presence of an inert gas. Thus, an acrylonitrile-rubber-vinyl compd. latex, coagulated and formed into strands was pelletized by screw extrusion in the presence of CO2. The product had Izod impact strength 2.57kg/cm2, yellowness index 28.
