  • Nitrile barrier resins and process for their manufacture
    Patent number: 4322510
    Abstract: Impact-resistant polymers having excellent color, clarity and low permeability to gases and vapors are prepared by polymerizing in a specified manner an olefinically unsaturated nitrile such as acrylonitrile, an ester of an olefinic acid such as methyl acrylate, or a vinyl ester such as vinyl acetate, and a vinyl aromatic monomer such as styrene optionally in the presence of a diene rubber.
