A polymer processing aid composition, a melt processable polymer composition that uses the polymer processing aid, and a method of improving the melt processability of a thermoplastic polymer are provided. The polymer processing aid composition comprises a multimodal fluoropolymer that preferably comprises interpolymerized units derived from an ethylenically unsaturated fluoromonomer tetrafluoroethylene and at least one ethylenically copolymerizable alpha-olefin monomer.
L'invention concerne une composition facilitant le traitement de polymères, une composition polymère traitable par fusion utilisant la composition facilitant le traitement de polymères et un procédé pour améliorer la capacité de traitement par fusion d'un polymère thermoplastique. La composition facilitant le traitement de polymères comprend un polymère fluoré multimodal qui comprend de préférence des unités interpolymérisées dérivées à partir d'un monomère fluoré tétrafluoréthylène éthyléniquement insaturé et au moins un monomère alpha-oléfine éthyléniquement copolymérisable.
