Abstract
A process for reducing free acrylonitrile monomer in nitrile polymers during melting which involves having an effective amount of an unsaturated fatty acid or a glyceride of oleic, linoleic and linolenic acid or compounds such as safflower and linseed oils as an acrylonitrile scavenger in admixture with the polymer during melting. Shaped products such as 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 minimal.
