CA 2519316

Compositions are provided having from 70 wt% to 95 wt% of a polymer selected from homopolymers and random copolymers of propylene and from 5 wt% to 30 wt% of a miscible hydrocarbon resin with a glass transition temperature greater than 20~C. The polymer has a heat of fusion of less than 50 J/g, a melt index (MI) of less than 20 dg/min, and contains stereoregular propylene crystallinity. Also provided are films containing such compositions, and articles, such as diapers or incontinence garments, including such films.

La présente invention concerne des compositions possédant de 70% à 95% en masse d'un polymère sélectionné dans des homopolymère et dans des copolymères aléatoires de propylène et de 5% à 30% en masse d'une résine de d'hydrocarbure miscible avec une température de transition vitreuse supérieure à 20·C. Ce polymère possède une chaleur de fusion inférieure à 50 J/g, un indice de fonte (MI) inférieur à 20 dg/min et, il contient une cristallinité de propylène stéréorégulière. Cette invention concerne aussi des films contenant ces compositions, des articles tels que des couches ou des vêtements pour incontinent comprenant ces films.
