Abstract
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.
