A composition comprising a first fluoropolymer and a second fluoropolymer. The first and second fluoropolymers are melt-processable, thermoplastic and have a melting point between 100° C. and 320° C. The first fluoropolymer has a relaxation exponent of from 0.93 to 1.0. The second fluoropolymer has a relaxation exponent of from 0.3 to 0.92. A composition comprising a first fluoropolymer having a long chain branching index of from 0 to 0.1 and a second fluoropolymer having a long chain branching index of at least 0.2. A composition comprising a core-shell polymer having a first polymer portion, wherein a polymer having an identical chemical structure as the first polymer portion has a relaxation exponent of from 0.93 to 1.0, and a second fluoropolymer portion, wherein a polymer having an identical chemical structure as the second fluoropolymer portion has a relaxation exponent of from 0.3 to 0.92. Methods for making compositions and methods of making articles from compositions.
