| 摘要 |
An object of the present invention is to provide a thermoplastic polymer composition which is flexible and capable of melt-molding and has excellent heat resistance, chemical resistance and oil resistance. The thermoplastic polymer composition comprises 10 to 95% by weight of a fluororesin (A) and 90 to 5% by weight of a crosslinked fluororubber (B), in which the fluororubber (A) comprises a fluorine-containing ethylenic polymer (a) having a melting point of 120° to 330° C. and the crosslinked fluororubber (B) is obtained by cross-linking dynamically at least one kind of fluororubber (b-1) or a fluorine-containing thermoplastic elastomer (b-2) in the presence of the fluororubber (A) and a crosslinking agent (C) under melting condition.
