The copolymer is derived from monomers comprising A) from 60 to 90% by weight of at least one nitrile, B) from 1 to 30% by weight of maleic anhydride and C) from 5 to 25% by weight of at least one representative of the group consisting of 1.) styrene or alpha -methylstyrene, 2.) an ester, 3.) an alpha -olefin, 4.) a vinyl ether, and 5.) vinyl acetate, where the percentages by weight of (A), (B) and (C) are based on the total weight of (A) + (B) + (C). The copolymers have excellent solvent resistance and, due to their high impact strength and low permeability to gases and vapours, are suitable for use in the packaging industry and are particularly suitable for the production of bottles, films, sheets, tubes and other types of container for liquids and solids. |
