Abstract[English]
A polymer composition includes: a matrix polymer component including a polystyrene polymer; and 0.005 wt% to 9 wt. %, based on the weight of the polymer composition, of a fluoropolymer component including a fibrillated fluoropolymer, a fibrillated fluoropolymer encapsulated by an encapsulating polymer, or a combination thereof. The polymer composition has a weight average molecular weight (Mw) below 193,000 grams per mole (g/mol) as determined according to gel permeation chromatography (GPC) using polystyrene standards. The polymer composition has a tensile modulus between 3300 and 3800 Megapascals (MPa) as tested in accordance with ISO 527. Methods for forming the polymer composition include passing a molten feed composition including the matrix polymer component and the fluoropolymer component through a die to form the polymer composition.[French]
L'invention concerne une composition polymère comprenant : un composant polymère matriciel comprenant un polymère de polystyrène; et de 0,005% en poids à 9% en poids, sur la base du poids de la composition polymère, d'un composant fluoropolymère comprenant un fluoropolymère fibrillé, un fluoropolymère fibrillé encapsulé par un polymère d'encapsulation, ou une combinaison de ceux-ci. La composition polymère a un poids moléculaire moyen en poids (Mw) inférieur à 193000 grammes par mole (g/mol) tel que déterminé selon la chromatographie par perméation de gel (GPC) à l'aide de normes de polystyrène. La composition polymère présente un module d'élasticité en traction compris entre 3300 et 3800 mégapascals (MPa) tel que testé conformément à la norme ISO 527. Des procédés de formation de la composition polymère comprennent le passage d'une composition d'alimentation fondue comprenant le composant polymère matriciel et le composant fluoropolymère à travers une matrice pour former la composition polymère.
