    摘要: The present invention describes synthesis of new fluorinated elastomers presenting very low glass transition temperatures, a good resistance to bases, petroleum and fuels and good properties for forming. These elastomers contain, by way of example, from 90 to 50 mole % of vinylidene fluoride (VDF) and from 10 to 50 molar % of perfluoromethyl vinyl ether (PMVE). In this precise case, they are prepared by radical copolymerisation of VDF and with PMVE in presence of various organic initiators such as for example the peroxides, the peresters or the diazo compounds.
