Title:
FLUORINE-CONTAINING COPOLYMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2013/015202
Kind Code:
A1
Abstract:
Provided is a fluorine-containing copolymer composition with which a molded body having excellent heat resistance and excellent stress crack resistance can be produced at high productivity.
This fluorine-containing copolymer composition contains ETFE and copper oxide, and the ETFE contains a repeating unit (A) that is derived from ethylene, a repeating unit (B) that is derived from tetrafluoroethylene, and a repeating unit (C) that is derived from another monomer. The molar ratio of the repeating unit (A) to the repeating unit (B) is from 38/62 to 44/56, and the repeating unit (C) is contained in an amount of 0.1-2.6% by mole relative to the total repeating units in the ETFE. The copper oxide content relative to the ETFE is 0.2-10 ppm. The volumetric flow rate of the fluorine-containing copolymer composition at 297˚C is 15-150 g/10 minutes.
