Method for granulating ethylene/tetrafluoroethylene copolymer

摘要

To provide a method for producing ETFE granules having a low content of an ethylene/tetrafluoroethylene copolymer oligomer and being excellent in handling efficiency. A method for granulating an ethylene/tetrafluoroethylene copolymer, which is characterized by stirring and granulating a slurry of an ethylene/tetrafluoroethylene copolymer together with water in the presence of both ethylene and tetrafluoroethylene at a granulation temperature of from 10 to 130° C. for a granulation time of from 30 to 240 minutes.
