To provide a fluorinated compound having an RF group with at most 6 carbon atoms, whereby a fluorinated polymer having a highly durable water/oil repellency can be produced, and an environmental load is little, and a fluorinated polymer and a fluorinated copolymer having a highly durable water/oil repellency and presenting little environmental load, obtainable by polymerizing such a fluorinated compound. A fluorinated compound represented by the following formula (I) and its polymer:
CH2═C(M)COO(CH2)nPhCOO(CH2)mCrF2r+1 (I)
(in the formula (I), M is a hydrogen atom, a methyl group or a halogen atom, n is an integer of from 0 to 2, Ph is a phenylene group, m is an integer of from 1 to 4, and r is an integer of from 1 to 6).
提供具有最多6个碳原子的RF基团的氟化合物,从而可以生产具有高耐久性的抗水/油性的氟化聚合物,并且环境负荷较小,通过聚合这种氟化合物可以获得具有高耐久性的抗水/油性和环境负荷较小的氟化聚合物和氟化共聚物。以下是用下式(I)表示的氟化合物及其聚合物:CH2═C(M)COO(CH2)nPhCOO(CH2)mCrF2r+1 (I)(在式(I)中,M是氢原子,甲基基团或卤素原子,n为0至2的整数,Ph为苯基团,m为1至4的整数,r为1至6的整数)。
