  • Extrudable thermoplastic hydrocarbon compositions
    Patent number: 5710217
    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.

  • Melt-processable fluoroplastic
    Patent number: 5527858
    Abstract: This invention provides a melt-processable fluoroplastic composition comprising a blend of a melt-processable thermoplastic fluoropolymer component of interpolymerized units derived from vinylidene fluoride and at least one ethylenically-unsaturated, copolymerizable, fluorinated comonomer, and a hydrocarbon polymer component comprising poly(oxyalkylene). The composition is useful for making shaped articles including tubing or film.
