A composition comprising: (i) a homopolymer of ethylene made by a high pressure process, and, based on 100 parts by weight of component (i), (ii) about 2 to about 15 parts by weight of a copolymer of ethylene and an acrylic acid ester or methacrylic acid ester, said ester being present in the copolymer in an amount of about 10 to about 30 percent by weight based on the weight of the copolymer; and (iii) about 0.03 to about 0.3 part by weight of a polyethylene glycol having a molecular weight in the range of about 1000 to about 100,000. L'invention concerne une composition renfermant: i) un homopolymère d'éthylène fabriqué selon un procédé à haute pression, sur la base de 100 parties en poids du composant i), ii) environ 2 à 15 parties en poids d'un copolymère d'éthylène et d'un ester d'acide acrylique ou d'un ester d'acide méthacrylique, cet ester étant présent dans le copolymère à hauteur de 10 à 30 % environ en poids, sur la base du poids dudit copolymère; et iii) environ 0,03 à 0,3 parties en poids d'un polyéthylèneglycol dont le poids moléculaire varie approximativement entre 1000 et 100 000.
