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.
