Provided are a fluororesin-containing composition having significantly improved fluidity and a method for producing the same. The fluororesin-containing composition contains 99.99 to 97% by mass of a fluororesin having a melting point of 205° C. to 225° C. and 0.01 to 2% by mass of a thermotropic liquid crystal polymer. The method for producing the fluororesin-containing composition includes kneading polychlorotrifluoroethylene and a thermotropic liquid crystal polymer at 285° C. to 320° C.

Fluorine-containing resin composition and method for production thereof

A resin composition including an aromatic polyether ketone resin (I), and a fluororesin (II), the fluororesin (II) being a copolymer of tetrafluoroethylene and a perfluoroethylenic unsaturated compound represented by the following formula (1):CF&#x2550;CF&#x2014;R&#x2003;&#x2003;(1)wherein Rrepresents &#x2014;CFor &#x2014;OR, and Rrepresents a C1 to C5 perfluoroalkyl group; the composition containing the aromatic polyether ketone resin (I) and the fluororesin (II) at a mass ratio (I):(II) of 95:5 to 50:50; the fluororesin (II) being dispersed as particles in the aromatic polyether ketone resin (I) and having an average dispersed particle size of 3.0 &#x3bc;m or smaller.
