Abstract
A fluorine-containing elastomer composition comprising a terpolymer of tetrafluoroethylene, perfluoro(lower alkyl vinyl ether) and perfluoro(ω-cyanoalkyl vinyl ether) and a bisaminophenyl compound represented by the following general formula as a curing agent: wherein A is an alkylidene group having 1 to 6 carbon atoms, a perfluoroalkylidene group having 1 to 10 carbon atoms, a SO2 group, an O group, a CO group, or a carbon-carbon bond capable of directly coupling two benzene rings; and X and Y each are a hydroxyl group or an amino group can give a rubbery vulcanization product with a good processability and good physical properties by a commercially available cross-linking agent free from any safety problem.
