Title:
ETHYLENE/TETRAFLUOROETHYLENE COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2011/007705
Kind Code:
A1
Abstract:
Disclosed is an ethylene/tetrafluoroethylene copolymer with excellent heat resistance and excellent flexibility. The ethylene/tetrafluoroethylene copolymer contains a repeating unit (A) based on tetrafluoroethylene, and a repeating unit (B) based on ethylene. Repeating unit (A)/repeating unit (B) = 66/34 to 75/25 (mole ratio). As an optional component, a repeating unit (C) based on the monomer represented by CH2=CX(CF2)nY (wherein X and Y are each independently either a hydrogen atom or a fluorine atom, and n is 2 to 8) is contained at 0.01 to 1 mol % with respect to the total number of moles of the repeating unit (A) based on tetrafluoroethylene and the repeating unit (B) based on ethylene. The volumetric flow rate measured at 297ºC is 4 to 1000 mm3/sec, and the modulus of elasticity is no more than 500 MPa.
