Claims19
A polymer obtained by polymerizing a compound of formula (1):
- wherein:
- ZA, ZB, ZC, ZD, and ZE each independently represent —CH(—OC(O)CT=CH2)—, —CF (—CHOC(O)CT=CH2)— or —CRARB—, provided that at least one of ZA to ZE is —CH(—OC(O)CT=CH2)— or —CF(—CH2OC(O)CT=CH2)—, and at least one of ZA to ZE is —CRARB—, wherein T is a hydrogen atom, a fluorine atom, a C1-3 alkyl group or a C1-3 fluoroalkyl group, and each of RA and RB is independently a fluorine atom, a C1-16 perfluoroalkyl group or a C1-16 perfluoroalkyl group comprising an etheric oxygen atom;
- WA and WB each independently represent a fluorine atom, a C1-16 perfluoroalkyl group or a C1-16 perfluoroalkyl group comprising an etheric oxygen atom;
- and
- n is 0, 1 or 2.
