Title (EN) TRANSPARENT OXYGEN-SCAVENGING COMPOSITIONS CONTAINING POLYESTERS COMPRISING A CYCLOBUTANEDIOL AND ARTICLES PREPARED THEREFROM
(FR) COMPOSITIONS TRANSPARENTES ABSORBANT L'OXYGÈNE CONTENANT DES POLYESTERS COMPRENANT UN CYCLOBUTANEDIOL ET ARTICLES PRÉPARÉS À PARTIR DE CELLES-CI
Abstract:
(EN) Disclosed are oxygen-scavenging polymer compositions having high transparency and low haze comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-l ,3-cyclobutanediol, a copolyamide or a transamidized, homogeneous blend of a least two polyamides, and a metal catalyst. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about -0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties.
(FR) L'invention concerne des compositions de polymère absorbant l'oxygène ayant une transparence élevée et un faible aspect trouble comprenant des mélanges non miscibles d'au moins un polyester comprenant un résidu de 2,2,4,4-tétraméthyl-1,3-cyclobutanediol et d'un copolyamide ou d'un mélange homogène transamidé d'au moins deux polyamides et un catalyseur en métal. Les composants du mélange non miscible ont des indices de réfraction qui diffèrent d'environ 0,006 à environ -0,0006. La faible différence en termes d'indices de réfraction permet l'incorporation de matière rebroyée dans la composition de polymère pour produire des articles formés transparents. Les mélanges de la présente invention sont utiles pour produire des articles formés tels que, par exemple, des feuilles, des films, des tubes, des bouteilles, des préformes et des profilés. Ces articles peuvent avoir une ou plusieurs couches et peuvent présenter de meilleures et excellentes propriétés de barrière et une bonne aptitude à être traités en phase fondue tout en conservant d'excellentes propriétés mécaniques.
