More Information
Summary:The invention concerns a certain class of polymers, their production into films and applications for their use. These polymers have unique properties which make them particularly well suited for use in polymeric films. These films are very useful in applications requiring heat sealability, particularly those applications containing an ionomer film. It has been discovered that polymers derived from metallocene catalyst systems surprisingly heat seal extremely well, as compared to polymer produced by conventional Ziegler-Natta catalysts, to a class of polymers known as ionomers. L'invention porte sur certaines classes de polymères, leur mise en films et leurs applications. Lesdits polymères présentent des propriétés uniques qui les rendent particulièrement bien adaptés à la fabrication de films, et au thermoscellement, en particulier dans les applications utilisant des films d'ionomères. On a constaté avec surprise que les polymères obtenus par des systèmes de catalyseurs métallocéniques se prêtaient particulièrement bien au thermoscellement sur les polymères de la classe des ionomères comparativement aux polymères obtenus à l'aide des catalyseurs usuels de Ziegler-Natta.
