US 12,221,544 B2 · Acrylonitrile-butadiene rubber composition, and laminate having layer of the composition

Abstract

An object of the present invention is to develop an NBR composition excellent in an adhesive strength with a saponified ethylene-vinyl acetate copolymer layer, and a laminate excellent in an adhesive strength of an NBR layer with a saponified ethylene-vinyl acetate copolymer layer; and the present invention relates to an acrylonitrile-butadiene rubber composition comprising an acrylonitrile-butadiene rubber and a silane-modified ethylene-vinyl acetate copolymer of 0 to 50 parts by mass with respect to 100 parts by mass of the acrylonitrile-butadiene rubber, and a laminate comprising an acrylonitrile-butadiene rubber layer comprising the composition and the saponified ethylene-vinyl acetate copolymer layer through an ethylene-vinyl acetate copolymer layer.
