Title
(EN) HETEROPHASIC POLYPROPYLENE WITH LOW CLTE AND HIGH STIFFNESS
(FR) POLYPROPYLÈNE HÉTÉROPHASIQUE AVEC CLTE FAIBLE ET UNE RIGIDITÉ ÉLEVÉE
Abstract
(EN)
Polyolefin composition (PO) comprising (a) a heterophasic propylene copolymer (HECO) comprising (a1) a polypropylene (PP) being the matrix of the heterophasic propylene copolymer (HECO) and (a2) an elastomeric propylene copolymer (E), said heterophasic propylene copolymer (HECO) has an intrinsic viscosity ratio of the xylene cold soluble (XCS) fraction and xylene cold insoluble (XCI) fraction [(XCS)/(XCI)] equal or below 1.6 and (b) more than 150 to equal or below 800 ppm of a nucleating agent (VP) selected from the group consisting of vinylcycloalkane polymers,vinylalkane polymers and mixtures thereof.
(FR)
La présente invention concerne une composition de polyoléfine (PO) comprenant (a) un copolymère de propylène hétérophasique (HECO) comprenant (a1) un polypropylène (PP) étant la matrice du copolymère de propylène hétérophasique (HECO) et (a2) un copolymère de propylène élastomère (E), ledit copolymère de propylène hétérophasique (HECO) a un rapport de viscosité intrinsèque de la fraction soluble dans le xylène froid (XCS) et la fraction insoluble dans le xylène froid (XCI) [(XCS)/(XCI)] égal ou inférieur à 1,6 et (b) plus de 150 à égal ou inférieur à 800 ppm d'un agent de nucléation (VP) choisi dans le groupe constitué de polymères de vinylcycloalcane, polymères de vinylalcane et des mélanges de ceux-ci.
