Title (EN) PROPYLENE POLYMER COMPOSITION AND FILMS MADE THEREFROM
(FR) COMPOSITION DE POLYMERE DE PROPYLENE ET FILMS FORMES A PARTIR DE LA COMPOSITION
Abstract:
(EN) A propylene polymer composition comprising a propylene homopolymer or a copolymer of propylene with an $g(a)-olefin having four or more carbon atoms, which homopolymer or copolymer has a high isotactic pentad fraction and an a narrow molecular weight distribution, polymerized in the presence of a metallocene catalyst, and, if necessary, further containing a nucleating agent. The composition has well-balanced rigidity and heat sealability which could not be attained in the prior art and is nonsticky and excellent in antiblocking properties. Films for packing foods or the like, obtained by molding the composition, keep high rigidity, antiblocking properties, film impact, and moldability.
(FR) L'invention concerne une composition de polymère de propylène comprenant un homopolymère de propylène ou un copolymère de propylène avec une $g(a)-oléfine possédant quatre atomes de carbone ou plus; cet homopolymère ou ce copolymère présente une fraction pentavalente isotactique et une répartition des poids moléculaires étroite, est polymérisé en présence d'un catalyseur de métallocènes et si nécessaire, contient en outre un agent de nucléation. La composition présente une rigidité équilibrée et une capacité d'adhérence à chaud qui ne pouvaient être obtenues dans les compositions antérieures, et est non adhésive et possède d'excellentes propriétés anti-adhérentes. Les films d'emballage d'aliments ou analogues, obtenus par moulage de la composition, gardent une grande rigidité, des propriétés antiadhérentes, des propriétés de résistance aux chocs, et une aptitude au moulage.
