Beschreibung
Zusammenfassung:	Provided is a composition for coating a separator for an electrochemical device, wherein the composition contains a polymer containing trifluoroethylene unit, a content of the trifluoroethylene unit in the polymer is 57 to 100 mol% based on all monomer units, and when the polymer contains an other monomer unit other than the trifluoroethylene unit, the other monomer includes at least tetrafluoroethylene, or tetrafluoroethylene and at least one monomer (α) selected from the group consisting of a fluorinated monomer, excluding trifluoroethylene and tetrafluoroethylene, and a polar group-containing monomer.
