Abstract

L'invention est relative à une feuille de matière synthétique formée d'un copolymère, caractérisée en ce qu'elle est formée d'un terpolymère comprenant, en poids, de 93,2 à 99,0 % d'unités de propylène, de 0,5 à 1,9 % d'unités d'éthylène et de 0,5 à 4,9 % d'unités d'une alpha -oléfine dont la molécule contient de 4 à 10 atomes de carbone, les comonomères étant pratiquement distribués statistiquement Elle concerne également le procédé de fabrication d'une telle feuille.The invention relates to a sheet of synthetic material formed of a copolymer, characterized in that it is formed of a terpolymer comprising, by weight, from 93.2 to 99.0% of propylene units, of 0.5 to 1.9% of ethylene units and from 0.5 to 4.9% of units of an alpha-olefin in which the molecule contains 4 to 10 carbon atoms, the comonomers being practically distributed statistically It also relates to the method of manufacturing such a sheet.
