FLUORINE-CONTAINING ELASTOMER |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a fluorine-containing elastomer capable of giving a vulcanizate having good vulcanized properties and compression set. SOLUTION: A fluorine-containing elastomer has a copolymerization composition of 45-75 mol.% tetrafluoroethylene, 50-25 mol.% perfluoro(lower alkyl vinyl ether) or perfluoro (lower alkoxy lower alkyl vinyl ether) and 0.1-5 mol.% perfluorounsaturated nitrile compound represented by the formula CF2 =CFO (CF2 )n OCF(CF3 )CN (wherein n is an integer of 2-5) and an intrinsic viscosity of 0.05-4 dl/g. |
