Formula (I) Q-O- [A -B] z - polymer [A-B '] z' -A-Q '. (Where A =-(X) a- OA '-(X') b- Where A ′ = perfluoropolyether chain; X, X ′ = — CF 2 —, —CF 2 CF 2 —; a, b = 0.1, provided that A is Q—O—. And b = 0 when A is connected to Q ′, and B is the formula — [(CR 1 R 2 —CR 3 R 4 ) j (CR 5 R 6 —CR 7 R 8 ) j ′ ] — derived from an olefin that can be homopolymerized by the radical route of (Ia), where j is an integer from 1 to 30 and j ′ is an integer from 0 to 29; However, on the condition that (j + j ′) is larger than 2 and smaller than 30, R 1 to R 8 are halogen, H, C 1 to C 6 (per) haloalkyl, C 1 to C 6 alkyl, C 1 to a C 6 oxy (per) fluoroalkyl, B '= a B, however, the least among R 1 to R 8 One has a different meaning than the R 1 to R 8 in the B, z, z 'is a number average molecular weight of the polymer of formula (I) is a value that is between 500～150,000 Yes, Q, Q ′ = C 1 -C 3 (per) fluoroalkyl or functional end group — (CFW) —D q -T k , W = F, CF 3 , k and q are integers K is in the range of 1-4, preferably 1 or 2, q is an integer and is equal to 0 or 1, provided that at least one of Q, Q ′ is a functional end group To do) |
