Core shell fluoropolymers with functional groups suitable for copper and electronic telecommunications articles

Abstract

Presently described are electronic telecommunication articles comprising core shell fluoropolymers comprising polymerized units of tetrafluoroethylene and no greater than 1 wt. % of polymerized units of comonomer comprising a functional group. The functional groups are typically selected from nitrile, halogen, sulfur oxide, perfluorinated alkyl ether, and carbonyl. The core shell fluoropolymer typically comprises at least 80, 85, 90, 95, 96, 97, 98, 99 wt. % or greater of polymerized units of tetrafluoroethylene. In some embodiments, the core shell fluoropolymer further comprises up to 20 or 25 wt. % of polymerized units of other comonomers, such as hexafluoropropylene (HFP). Also described are methods of making a coated substrate, coated substrates, and core shell fluoropolymers.
