Abstract
Copolymers of acrylonitrile and propylene are produced by the process of the instant invention. This process comprises polymerizing (1) a major portion of an olefinically unsaturated nitrile monomer with (2) a minor portion of propylene, in the presence of a free radical initiator, while maintaining the molar ratio of propylene to the olefinically unsaturated nitrile during polymerization at a ratio greater than the molar ratio of propylene to the olefinically unsaturated nitrile in the final polymer.
