Abstract: To provide a resin composition formable into a molded body excellent in friction properties and heat resistance and a molded body.
A resin composition including: a non-fluorinated thermoplastic resin; a first tetrafluoroethylene polymer; and a second tetrafluoroethylene polymer having a melting point higher than or equal to 260° C. and lower than a melting point of the first tetrafluoroethylene polymer, wherein, relative to the total mass of the non-fluorinated thermoplastic resin, the first tetrafluoroethylene polymer and the second tetrafluoroethylene polymer, the content of the first tetrafluoroethylene polymer is from 4.0 to 32.0 mass %, and the content of the second tetrafluoroethylene polymer is from 0.5 to 10.0 mass %, and wherein the resin composition is obtained by melt-mixing a mixed powder of first particles of the first tetrafluoroethylene polymer and second particles of the second tetrafluoroethylene polymer with a powder of the non-fluorinated thermoplastic resin.

Abstract: A resin composition that yields a molded article excellent in impact resistance and exhibits excellent moldability. The resin composition includes at least one type of melt-moldable thermoplastic resin A selected from a polyarylate, a polyether sulfone, a polyaryl sulfone, an aromatic polyetheramide, an aromatic polyetherimide, a polyphenylene sulfide, a polyaryletherketone, a polyamideimide, and a liquid crystal polyester, and a fluorine-containing elastomer B having a terminal functional group. The volume ratio of the thermoplastic resin A and the fluorine-containing elastomer B is from 99:1 to 50:50, and the fluorine-containing elastomer B is dispersed in the thermoplastic resin A. A molded article or the like can be obtained from the resin composition.
