Abstract
To provide a perfluoroelastomer, which is excellent in low temperature properties, which does not lose value as a rubber and which is free from a decrease of the productivity, a perfluoroelastomer composition, a crosslinked rubber product, and a method for producing a perfluoroelastomer. A perfluoroelastomer comprising structural units (a) derived from tetrafluoroethylene, structural units (b) derived from a perfluoroalkyl vinyl ether represented by the formula (1) (such as perfluoromethyl vinyl ether) and structural units (c) derived from a perfluorooxaalkyl vinyl ether represented by the formula (2) (such as CF═CFOCFCFOCFCFOCFCF).
