Abstract
Abstract A fluorine-containing elastomer having excellent low temperature resistance and oil resistance comprises ethylene units (E) and fluorovinyl ether units (FV) having the formula CF<sub>2</sub> = CFOX (X represents a C<sub>1</sub> - C<sub>s</sub> perfluoroalkyl group which can have one or more ether bond) at a molar ratio of (E) to (FV) of 95 : 5 to 30 : 70 and at a total content of (E) and (FV) of at least 70 mole %.
