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 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)nPhXPhZCrF2r+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, X is CH2O or OCH2, Z is a single bond, a C1-4 alkylene group containing an etheric oxygen atom, or COO(CH2)m (wherein m is an integer of from 1 to 4), and r is an integer of from 1 to 6).
提供一种具有最多 6 个碳原子的 RF 基团的含氟化合物,通过该含氟化合物的聚合可制得一种具有高持久性防水/防油性能且环境负荷小的含氟聚合物,以及一种具有高持久性防水/防油性能且环境负荷小的含氟聚合物。由下式(I)表示的含氟化合物及其聚合物:
CH2=C(M)COO(CH2)nPhXPhZCrF2r+1 (I)
式(I)中,M 是氢原子、甲基或卤素原子,n 是 0 至 2 的整数,Ph 是亚苯基,X 是 CH2O 或 OCH2,Z 是单键、含有醚氧原子的 C1-4 亚烷基或 COO(CH2)m(其中 m 是 1 至 4 的整数),r 是 1 至 6 的整数)。
