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

摘要

Fluorine-containing thermoplastic elastomeric compositions comprising: (A) a 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° C., and (2) about 10 to 100 weight percent of block thermoplastic elastomer having a melt temperature greater than about 150° C.; and (B) a disperse phase comprising particles or domains of cured, fluoroelastomer composition. Such compositions are preferably prepared by dynamically vulcanizing the ingredients of the fluorine-containing thermoplastic elastomeric composition.
