<p>The inclusion of small amounts of epoxidised vegetable oils into high nitrile copolymers produces compositions of higher impact resistance. Representative oils are epoxidised soybean oil, linseed oil or butyl linseed oil. They are incorporated in an amount of from 0.1 to 20 parts by weight per 100 parts by weight of high nitrile polymer. A preferred polymer is a nitrile rubber-modified copolymer of 75% by weight of acrylonitrile and 25% by weight of methyl acrylate. </p> |
