Title (EN) COPOLYESTER RESIN COMPOSITION WITH IMPROVED MELT FLOW PROPERTIES
(FR) COMPOSITION DE RÉSINE DE COPOLYESTER PRÉSENTANT DES PROPRIÉTÉS DE FLUIDITÉ AMÉLIORÉES
Abstract:
(EN) A copolyester resin composition is described. The copolyester resin composition includes a linear copolyester polymer and a linear copolyester oligomer. A particularly suitable linear copolyester oligomer is an intermediate of the copolyester polymer. The composition exhibits improved melt flowability and is therefore particularly useful in the manufacture of products made via injection molding methods. A process for forming the composition is also described.
(FR) L'invention concerne une composition de résine de copolyester. La composition de résine de copolyester comprend un polymère de copolyester linéaire et un oligomère de copolyester linéaire. Un oligomère de copolyester linéaire particulièrement approprié est un intermédiaire du polymère de copolyester. La composition présente une aptitude à la fluidité améliorée et est donc particulièrement avantageuse dans la préparation de produits préparés par l'intermédiaire de procédés de moulage par injection. L'invention concerne également un procédé de formation de la composition.
