Abstract: The present invention relates to an adhesive polyethylene composition comprising (A) from 60 to 90 wt % of a non-elastomeric polyethylene; (B) from 9.0 to 38 wt % of an ethylene based elastomer being a copolymer of ethylene and alpha-olefin comonomer units having from 4 to 12 carbon atoms; wherein onto component (A) or components (A) and (B) an acid grafting agent (C) has been grafted in an amount of from 0.01 to 3.0 wt %, all based on the total weight of the adhesive polyethylene composition, a multi-layer structure comprising said adhesive polyethylene composition and the use of said adhesive polyethylene composition for the production of a multi-layer structure.

Abstract: The present invention relates to an adhesive polyethylene composition comprising (A) from 60 to 90 wt % of a non-elastomeric polyethylene being a terpolymer of ethylene with two different alpha-olefin comonomer units selected from alpha-olefins having from 4 to 12 carbon atoms; (B) from 9.0 to 38 wt % of an elastomer; wherein onto component (A) or components (A) and (B) an acid grafting agent (C) has been grafted in an amount of from 0.01 to 3.0 wt %, all based on the total weight of the adhesive polyethylene composition, a multi-layer structure comprising said adhesive polyethylene composition and the use of said adhesive polyethylene composition for the production of a multi-layer structure.

Abstract: The present invention is a process for producing copolymers of ethylene and alpha-olefins having from 4 to 10 carbon atoms in three polymerization stages where a low molecular weight copolymer of ethylene is produced in two of the stages and a high molecular weight copolymer in one of the stages. The resulting copolymers have a low content of extractable material and can be extruded to films which can be used in food contact applications.
