Compositions containing at least 60% by weight of at least one copolymer (A) of ethylene and at least one alpha-olefin with 3 to 10 carbon atoms, and no more than 40% by weight of at least one copolymer (B) based on ethylene and at least one anhydride of an unsaturated dicarboxylic acid, characterized in that: (i) copolymer (A) has a density between 0.850 and 0.890, (ii) copolymer (B) contains at least 80 mol-% of units derived from ethylene and at least 0.1 mol-% of units derived from the anhydride of an unsaturated dicarboxylic acid, and (iii) at least one of copolymers (A) and (B) is modified by means of an effective amount either of a free-radical initiator if the modification involves copolymer (A), or of at least one compound capable of reacting with the anhydride functions of copolymer (B). The procedure for their preparation is comprised of creating a homogeneous mixture of copolymer (A), copolymer (B) of the initiator and/or compound capable of modifying copolymer (A) and copolymer (B), respectively, in a mixer at a temperature between about 150 DEG and 290 DEG C. Industrial articles obtained by transformation of the aforementioned composition.
