  • Fluoropolymer containing a small amount of bromine-containing olefin units
    Patent number: 4035565
    Abstract: A novel fluoropolymer can be made by copolymerizing a small amount (e.g. about 0.5-3 mole %) of bromotrifluoroethylene or bromotetrafluorobutene with certain combinations of monomers comprising selected fluorine-containing compounds. A fluoropolymer composition useful in the manufacture of cured fluoropolymer articles can be made by mixing the resulting fluoropolymer or a closely related fluoropolymer with an organic peroxide such as a dialkyl peroxide, and preferably also adding a divalent metal oxide and/or hydroxide and a suitable coagent such as triallyl isocyanurate.
