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

Coextrusion binder, its use in a multilayer structure and the structure

The invention provides a film having low permeability to hydrocarbons comprising at least one layer (i) formed of a polyamide/polyolefin alloy having a polyamide matrix and at least one layer (ii) formed of a polyolefin. The invention also provides a release film for a sheet molding compound consisting of said film, as well as a packaging for expandable polystyrene formed of said film.

Film having low permeability to hydrocarbons

The present invention provides a sheet molding compound consisting in a sandwich structure comprising a central layer of reinforced uncured heat hardenable sheet molding compound; and two outer layers of a release film having low permeability to hydrocarbons comprising at least one layer (i) of a polyamide/polyolefin alloy having a polyamide matrix and at least one layer (ii) of a polyolefin.
