Patent ID: 8829132

Claim:
An ethylene/tetrafluoroethylene copolymer consisting of repeating units (A) based on tetrafluoroethylene, (B) based on ethylene in a ratio of repeating units (A)/repeating units (B)=70.9/29.1 to 75/25 (molar ratio), and as an optional component, repeating units (C) based on a monomer represented by CH 2 ═CX(CF 2 ) n Y wherein each of X and Y which are independent of each other is a hydrogen atom or a fluorine atom, and n is from 2 to 8 in an amount of from 0 to 1 mol % based on the total number of moles of the repeating units (A) and (B), said ethylene/tetrafluoroethylene copolymer having a volume flow rate measured at 297° C. of from 4 to 1,000 mm 3 /sec and an elastic modulus of at most 500 MPa.
