Title (EN) PROPYLENE POLYMER COMPOSITIONS
(FR) COMPOSITIONS DE POLYMÈRE DU PROPYLÈNE
Abstract: front page image
(EN)A propylene polymer composition comprising (percent by weight): A) 65%-85% of a propylene copolymer containing from 2.0% to 5.0% of ethylene derived units having MFR L (Melt Flow Rate according to ASTM 1238, condition L, i.e. 230°C and 2.16 kg load) from 0.5 to 50 g/10 min and a melting temperature Tm ranging from 146°C to 155°C; B) 15%-35%, of a copolymer of ethylene and propylene with from 74% to 87%, of ethylene derived units; the composition having the intrinsic viscosity of the fraction soluble in xylene ranging from 0.8 to 1.2 dl/g preferably from 0.9 to 1.1 dl/g.
(FR)L'invention porte sur une composition de polymère du propylène comprenant (en pourcentage en poids) : A) 65 %-85 % d'un copolymère du propylène contenant de 2,0 % à 5,0 % de motifs issus de l'éthylène ayant un MFR L (indice de fluage à l'état fondu selon la norme ASTM 1238, dans les conditions L, c'est-à-dire à 230°C et sous une charge de 2,16 kg) de 0,5 à 50 g/10 min et une température de fusion Tm allant de 146°C à 155°C ; B) 15 %-35 % d'un copolymère de l'éthylène et du propylène comprenant de 74 % à 87 % de motifs issus de l'éthylène ; la composition ayant une viscosité intrinsèque de la fraction soluble dans le xylène allant de 0,8 à 1,2 dl/g, de préférence de 0,9 à 1,1 dl/g.
