Abstract
PURPOSE: A fluorine-containing copolymer that contains tetrafluoroethylene units and specific fluoroaryl ether units in a specific amount, thus giving an elastic material with high resistance to cold and oil.
CONSTITUTION: (A) the unit based on tetrafluoroethylene and (B) the other unit based on a fluoroaryl ether of formulaI(Rf is fluorine-containing group of 2W10 carbon atoms) are contained as essential components and they are copolymerized so that the molar ratio of A/B becomes 90/10W10/90 and the total content of A and B becomes more than 70mol% to give the objective copolymer. The Rf in component B is preferably a group of formula II and/or formula III and the copolymer preferably has an intrinsic viscosity of higher than 0.1dl/g, when measured in tetrahydrofuran at 30°C.
