Abstract
The present invention provides a fluorinated polymer excellent in the crosslinking reactivity, crosslinked rubber physical properties and chemical resistance, and its crosslinked rubber. A fluorinated polymer comprising repeating units (a) based on at least one monomer selected from the group consisting of ethylenic unsaturated compounds each having a hydroxyphenyl group, repeating units (b) based on at least one fluoromonomer selected from the group consisting of tetrafluoroethylene, hexafluoropropylene, vinylidene fluoride, 3,3,3-trifluoropropene, 1,3,3,3-tetrafluoropropene, 1,1,2-trifluoroethylene, vinyl fluoride, 1,2-difluoroethylene and CF═CF—O—R(wherein Ris a Csaturated perfluoroalkyl group or a perfluoro(alkoxyalkyl) group) and, if necessary, repeating units (c) based on at least one hydrocarbon monomer selected from the group consisting of ethylene, propylene and CH═CH—O—R.
