Title (EN) COMPOSITIONS INCLUDING COPOLYMERS OF VINYLIDENE FLUORIDE AND TETRAFLUOROETHYLENE AND METHODS OF USING THE SAME
(FR) COMPOSITIONS COMPRENANT DES COPOLYMÈRES DE FLUORURE DE VINYLIDÈNE ET DE TÉTRAFLUOROÉTHYLÈNE ET PROCÉDÉS POUR LEUR UTILISATION
Abstract:
(EN) A composition includes a thermoplastic fluoropolymer having vinylidene fluoride units in an amount of at least 30 mole percent and tetrafluoroethylene units in an amount of at least 5 mole percent. The thermoplastic fluoropolymer is free of hexafluoropropylene units or comprises less than 5 mole percent hexafluoropropylene units. The composition further includes at least one of a non-fluorinated, thermoplastic polymer as a major component of the composition or a polymer processing additive synergist. A method of reducing melt defects during the extrusion of a polymer is also provided. Use of the thermoplastic fluoropolymer as a polymer processing additive is also provided.
(FR) L'invention concerne une composition comprenant un fluoropolymère thermoplastique présentant des motifs de fluorure de vinylidène en une quantité d'au moins 30 pour cent en mole et des motifs de tétrafluoroéthylène en une quantité d'au moins 5 pour cent en mole. Le fluoropolymère thermoplastique est dépourvu de motifs hexafluoropropylène ou comprend moins de 5 pour cent en mole de motifs hexafluoropropylène. La composition comprend en outre au moins un polymère thermoplastique non fluoré en tant que constituant principal de la composition ou un synergiste additif de traitement de polymères. L'invention porte en outre sur un procédé de réduction des défauts de fusion lors de l'extrusion d'un polymère. L'invention concerne également l'utilisation du fluoropolymère thermoplastique comme additif de traitement de polymères.
