発明の名称 (英語) Fluorinated 1,3-dioxolane compounds, fluorinated polymers of the compounds, and optical or electrical materials comprising the polymers
発明の概要(英語) (US8168808)
A production method of fluorinated compounds, for producing a compound represented by formula (3) in a fluorine-based solution in a flow of fluorine gas after reaction of at least one type of compounds represented by formula (1) and at least one type of compounds represented by formula (2).
Similarly, fluorinated compounds represented by formula (4) prepared by the fluorination of compounds obtained by the reaction of formula (1) and formula (2)′.
The fluorinated polymers obtained by the polymerizations of formula (3) and (4) compounds are useful as an optical or electrical materials. wherein R1, R2, R3, R4, Rff1, Rff2, Rff3, Rff4, X, Y, Z, and n are defined in the specification respectively.
特許請求の範囲(英語) [claim1]
1. A fluorinated compound represented by the following formula (4):
wherein Rff1 and Rff2 each independently represents a fluorine atom or a perfluoroalkyl group having 1 to 7 carbon atoms, wherein at least one of Rff1 and Rff2 represents the perfluoroalkyl group, and n represents an integer from 1 to 4.
[claim2]
5. A compound represented by the following formula (6):
wherein X represents a hydrogen atom or a fluorine atom, Y represents a hydrogen atom, an alkyl group having 1 to 7 carbon atoms, or a polyfluoroalkyl group having 1 to 7 carbon atoms, R3 or R4 each independently represents a hydrogen atom, an alkyl group having 1 to 7 carbon atoms or a polyfluoroalkyl group having 1 to 7 carbon atoms, and n represents an integer from 1 to 4.
[claim3]
2. A fluorinated polymer obtained by polymerization of the fluorinated compound according to claim 1.
[claim4]
3. An optical or electrical material comprising the fluorinated polymer according to claim 2.
[claim5]
4. An optical or electrical material according to claim 3, wherein the optical material is optical wave guides, an optical lens, a prism, a photo mask, or an optical fiber.
