Abstract
Peroxide-curable fluorocarbon elastomers having interpolymerized units derived from a cure site monomer containing bromine or iodine. The fluorocarbon elastomer gums are prepared by copolymerizing with the principal monomers normally used in preparing fluorocarbon elastomers, e.g. vinylidene fluoride, hexafluoropropene, and (optionally) tetrafluoroethylene, a small amount of a novel cure site monomer which is a vinyl ether in which at least one of the two vinylic (or double-bonded) carbon atoms thereof is bonded to at least one bromine or iodine atom, e.g. CF.sub.3 CH.sub.2 OCF.dbd.CFBr. The cured fluorocarbon elastomers of this invention have useful properties normally associated with fluorocarbon elastomers, such as acid resistance, thermal stability, and high tensile strength. These properties of shaped articles made from these fluorocarbon elastomers are not adversely affected upon exposure to high temperatures for extended periods.
