PROBLEM TO BE SOLVED: To provide a copolymer composition excellent in mechanical durability and melt moldability by using a small amount of a perfluoro(alkyl vinyl ether). SOLUTION: The copolymer composition is obtained by kneading 30-35 wt.% of a polytetrafluoroethylene with 70-45 wt.% of a copolymer of 95-90 wt.% of tetrafluoroethylene and 5-10 wt.% of a perfluoro(alkyl vinyl ether) in a molten state. The copolymer has a melt flow rate at 372±1°C of 0.1-1.7 g/10 min, and the polytetrafluoroethylene has a melt flow rate at 372±1°C of 1 g/10 min or higher. COPYRIGHT: (C)2004,JPO
