Abstract
(EN)
Provided are a fluorine-containing resin composition having a highly improved fluidity, and a method for producing same. The present invention relates to a fluorine-containing resin composition that characteristically comprises 99.99-97 mass% of a fluororesin having a melting point of 205°C-225°C and 0.01-2 mass% of a thermotropic liquid crystal polymer. The present invention also relates to a method for producing a fluorine-containing resin composition, comprising a step for kneading a polychlorotrifluoroethylene with a thermotropic liquid crystal polymer at 285°C-320°C.
