Abstract: An adhesive composition of at least one ethylene polymer or copolymer, wherein at least one first polymer or copolymer including the unsaturated carboxylic acid ester type comonomer is copolymerized in a continuous high-pressure tubular reactor, while a second polymer or copolymer including the functional comonomer is copolymerized by either autoclave or tubular continuous high-pressure radical means; the first and second polymer or copolymer possibly being of one and the same polymer/copolymer. Also, a multilayer structure that incorporates the adhesive composition and a particular process for obtaining this composition.

Abstract: An adhesive composition that can be used in an extrusion-coating process for application to a support or in an extrusion-laminating process in order to bond several supports of different or identical nature to one another, over a wide temperature range, including: from 91% to 98% by weight of the composition, of a copolymer of ethylene and of alkyl acrylate; at least one tackifying resin; processing aids, wherein the tackifying resin represents between 1.5% and 5.5% of the weight of the composition and the processing aids represent between 0.5% and 3.5% of the weight of the composition and the anti-blocking agent represents, in the processing aids, at least 60% by weight of the aids. Also, a film of the composition and a multilayer structure that includes this film.
