PURPOSE:To produce, industrially easily and at a low cost, the title compsn. excellent in gas barrier properties without detriment to the mechanical properties characteristic of a conventional nitrile resin compsn. CONSTITUTION:The title compsn. is produced by mixing an emulsion contg. 2-30 pts.wt. high-acrylonitrile (co)polymer obtd. by the emulsion (co)polymn. of 80-100wt.% acrylonitrile with 0-15wt.% at least one monomer selected from 1-6C alkyl acrylates and methacry1ates with an emulsion contg. 70-98 pts.wt. low-acrylonitrile copolymer obtd. by the emulsion copolymn. of 50-80wt.% acrylonitrile with 20-50wt.% at least one monomer selected from 1-6C alkyl acrylates and methacrylates, and coagulating the resulting mixture. |
