FLUORINE COMPOUND, FLUOROPOLYMER, AND PROCESS FOR PRODUCING THE SAME

摘要

The present invention provides a fluorinated compound having functional groups in a high concentration so that adequate characteristics of the functional groups can be obtained and having high transparency in a wide wavelength region, a fluoropolymer, and a process for its production. The present invention provides a fluorinated diene represented by the following formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒCF 2 =CFCH 2 CH(C (R 1 )(R 2 )(OH))CH 2 CH=CH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein each of R 1 and R 2 which are independent of each other, is a fluorine atom or a fluoroalkyl group having at most 5 carbon atoms.
