Fluorine-containing elastomer composition

摘要

A fluorine-containing elastomer composition, which comprises a terpolymer of tetrafluoroethylene, perfluoro(lower alkyl vinyl ether) and a perfluoro unsaturated nitrile compound represented by the following general formula: CF2=CFO(CF2)nOCF(CF3)CN , wherein n is an integer of 2 to 5, and a bis(aminophenyl) compound represented by the following general formula as a cross-linking agent: <CHEM> , wherein A is an alkylidene group having 1 to 6 carbon atoms or a perfluoroalkylidene group having 1 to 10 carbon atoms and X and Y are a hydroxyl group or an amino group, can produce vulcanized products having good vulcanization physical properties and a good compression set.
