CA 2346072

Ethylene copolymer compositions that are useful for fabricating films and molded articles are disclosed. These compositions contain a combination of metal ions providing superior scratch and abrasion resistance than the individual composition containing only a single metal ion. These compositions comprise a copolymer of ethylene and 10-30 % by weight of acrylic acid or methacrylic acid which is neutralized from 10-99.9 % with a combination of at least two ions selected from the group consisting of Na, Zn, Li, Mg and Ca in a specific ratio. The compositions are useful for packaging abrasive goods and as transparent top layers for floors, wall covers or sporting goods.

L'invention concerne des compositions de copolymère d'éthylène utiles à la fabrication de films et d'articles moulés. Ces compositions contiennent une combinaison d'ions métalliques présentant une résistance supérieure à l'abrasion qu'une composition ne contenant qu'un ion métallique. Ces compositions contiennent un copolymère d'éthylène et 10-30 en poids d'acide acrylique ou d'acide méthacrylique, neutralisé de 10 à 99,9 avec une combinaison d'au moins deux ions choisis dans le groupe comprenant Na, Zn, Li, Mg et Ca dans un rapport spécifique. Lesdites compositions sont utilesour emballer des produits abrasifs et en tant que revêtements supérieurs de sols, revêtements muraux ou équipements sportifs.
