Abstract
An adhesive ethylene copolymer resin composition blend of a modified ethylene/&agr;-olefin copolymer obtained by graft-modifying an unmodified linear ethylene/&agr;-olefin copolymer comprising ethylene and an a-olefin of 3 to 20 carbon atoms with an unsaturated carboxylic acid or its derivative, or the unmodified ethylene/&agr;-olefin copolymer and the modified ethylene/&agr;-olefin copolymer and an olefin elastomer (F) The linear ethylene/&agr;-olefin copolymer being prepared by the use of an olefin polymerization catalyst including a Group IV transition metal compound (a) containing a ligand having cyclopentadienyl skeleton and an organoaluminum oxy-compound (b). The adhesive ethylene copolymer resin composition can be used as a layer to form a laminate with a layer of a polar material or a layer of a metal. The polar material layer can be a layer of an ethylene/vinyl alcohol copolymer, a layer of a polyamide or a layer of a polyester.
