POLYMER PROCESSING ADDITIVE CONTAINING A MULTIMODALFLUOROPOLYMER AND A MELT PROCESSABLE THERMOPLASTIC POLYMER COMPOSITION EMPLOYING THE SAME

摘要

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.
