Abstract: A polymer composition includes a non-fluorinated, thermoplastic polymer and a minor amount of a fluoropolymer combined with the non-fluorinated polymer. A polymer processing additive composition that includes a fluoropolymer and a polymer processing additive synergist is also disclosed. The fluoropolymer includes diads represented by formula —CF2-CF(R)—CH(R′)—CF(R″)— in a range from about 23 mole percent to about 50 mole percent. Each R is independently —CF3, —Rf, or —ORf, each R′ and R″ are independently H, F, CF3, or —Rf, and each Rf is independently a perfluoroalkyl group having from 1 to 12 carbon atoms and optionally interrupted by one or more —O— groups. A method of reducing melt defects during the extrusion of a polymer is also disclosed.

Abstract: Electronic telecommunication articles are described comprising a crosslinked fluoropolymer layer. In typical embodiments, the crosslinked fluoropolymer layer is a substrate, patterned (e.g. photoresist) layer, insulating layer, passivation layer, cladding, protective layer, or a combination thereof. Also describes are methods of making an electronic telecommunications article and method of forming a patterned fluoropolymer layer. The fluoropolymer preferably comprises at least 80, 85, or 90% by weight of polymerized units of perfluorinated monomers and cure sites selected from nitrile, iodine, bromine, and chlorine. Illustrative electronic communication articles include integrated circuits, printed circuit boards, antennas, and optical fiber cables. Fluoropolymer compositions are also described.
