Polymer blend composition of fluorinated elastomers, thermoplastic polymers and thermoplastics elastomers

Fluorine-containing, thermoplastic elastomer compositions comprising:

• (A) a continuous phase comprising the minor portion of the composition by weight, the continuous phase comprising:
• (1) about 0 to 90 weight percent of thermoplastic polymer having a melt temperature or glass transition temperature greater than about 150.degree. C. that is selected from the group consisting of:
• linear aliphatic polyamides, polyalkyleneterephthalates, polyimides, polyamideimides, polysulfones, polyetherimides, polycarbonates, polyethersulfones, polyetherketones, polyphenylenes, poly(phenylene sulfides), poly(phenylene oxides), polyetherether ketones and mixtures thereof;
• and
• (2) about 10 to 100 weight percent of thermoplastic elastomer that is selected from the group consisting of block copolymers having polyester and polyether blocks, polyamide and polyether blocks, and mixtures of such block copolymers and has a melt temperature greater than about 145.degree. C.;
• and
• (B) a disperse phase comprising the major portion of the composition by weight, the disperse phase comprising particles or domains of cured, fluorinated elastomer composition, wherein the fluorinated elastomer composition comprises an elastomer copolymer of one or more ethylenically unsaturated fluoromonomers and, optionally, one or more olefin monomers.
