Abstract
This invention provides a melt-processable composition comprising, in admixture: (1) one or more melt-processable thermoplastic hydrocarbon polymers as the major component of the composition by weight, and, as a minor component of the composition by weight, (2) an effective amount of a chemically-resistant, fluoropolymer process aid to improve the processability of the composition. The fluoropolymer process aid contains at least about 50 weight percent of fluorine and comprises one or more fluoropolymers which are essentially completely ethylenically saturated.
