Abstract
The invention relates to a coextrusion binder obtained by grafting a mixture of a copolymer of ethylene and of an elastomer of EPR type with an unsaturated carboxylic acid anhydride or its derivatives. The grafted mixture is optionally diluted in another copolymer of ethylene. The binder is useful in preparing polyolefin/binder/polyamide or EVOH structures. These structures are useful in preparing rigid hollow bodies
