摘要：
To provide a fluorinated elastomer from which it is possible to produce a crosslinked article excellent in cold resistance and excellent in mechanical strength; a fluorinated elastomer composition containing said elastomer; and a fluorinated elastomer crosslinked article obtained by molding and crosslinking said composition. The fluorinated elastomer comprises units (A) based on vinylidene fluoride and units (B) based on a perfluorovinyl ether represented by CF 2 =CF-O-R f , and has iodine atoms at main chain terminals, wherein the molar ratio [(A)/(B)] of units (A) to units (B) is from 88/12 to 50/50. In the formula, R f is a C 1-20 perfluoroalkyl group having a branched structure, or a C 2-20 perfluoroalkyl group having a branched structure and also having an etheric oxygen atom between carbon atoms.
