Abstract
A process for reducing free acrylonitrile monomer in nitrile copolymers during melting which involves having an effective amount of an acrylonitrile scavenger selected from the group consisting of unsaturated fatty acid aldehydes, and esters formed by the reaction of a short chain olefinic alcohol with a fatty acid or cyanuric acid in admixture with the copolymer during melting. Shaped products such as pellets, preforms, containers, film, sheet, etc., formed from such melt are well suited for packaging food, beverages, pharmaceuticals, cosmetics, etc., in that residual acrylonitrile monomer in the walls of such products is reduced over that present in the absence of such a scavenger.
