Abstract
Improved two-component blends which exhibit good adhesion to 4-methylpentene-1 polymers and vinyl alcohol polymers and which may be used as an adhesive interlayer when laminating layers of the polymers are provided. Ethylene-alkyl acrylate copolymers, preferably ethylene n-butyl acrylate copolymers, and modified propylene polymers, preferably maleic anhydride grafted statistical propylene-ethylene copolymers and propylene-ethylene impact copolymers, are combined to obtain the blends of the invention. Useful laminated structures comprised of a layer of poly-4-methylpentene-1 homopolymer or copolymer, a layer of the adhesive blend and a layer of ethylene-vinyl alcohol copolymer with one or more optional layers, such as a paperboard, are also disclosed.
