Abstract
The present invention provides a perfluoroether fluororubber and a preparation method therefor and use thereof. The perfluoroether fluororubber is prepared by a stepwise polymerization method, wherein polymerization monomers in each step of polymerization comprise tetrafluoroethylene and a perfluoroalkyl vinyl ether. The preparation method for the perfluoroether fluororubber provided in the present invention can shorten polymerization time and improve production efficiency, and the finally obtained perfluoroether fluororubber is good in processability, high in strength, low in hardness and compression deformation and good in medium resistance.
