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.
Claims6
A fluororesin-containing composition consisting of:
- 99.5 to 99.99% by mass of a fluororesin having a melting point of 205° C. to 225° C.;
- and
- 0.01 to 0.5% by mass of a thermotropic liquid crystal polymer,
- wherein the thermotropic liquid crystal polymer is a copolymer of para-hydroxybenzoic acid and ethylene terephthalate, and
- the thermotropic liquid crystal polymer contains the para-hydroxybenzoic acid in an amount of 20 to 80 mol %.
A fluororesin-containing composition comprising 99.5% by mass or more of polychlorotrifluoroethylene based on 100% by mass of a total of the fluorineresin-containing composition and 0.1 to 0.5% by mass of a thermotropic liquid crystal based on 100% by mass of the total of the fluorineresin-containing composition, and having a melt flow rate MFR at 280° C. of 3 to 40 g/10 min, and
- wherein the thermotropic liquid crystal polymer is a copolymer of para-hydroxybenzoic acid and ethylene terephthalate, and
- the thermotropic liquid crystal polymer contains the para-hydroxybenzoic acid in an amount of 20 to 80 mol %.
