Abstract
A fluorine-containing spiroacetal compound represented by the following formula (A): wherein X represents >C(CF3)(Y) or >C=CF2, in which Y represents -CF2OCOR<1>, -COOR<2>, -COF, or -CH2OR<3>, R<1> represents an alkyl or cycloalkyl group having at least one fluorine atom, R<2> represents a hydrogen atom, an alkali metal, an alkaline earth metal, an alkyl group, or a cycloalkyl group, and R<3> represents a hydrogen atom or an acyl group; wherein the alkyl or cycloalkyl group for R<1> may have a substituent other than fluorine atom; the alkyl or cycloalkyl group for R<2> may have a substituent; and the acyl group for R<3> may have a substituent.
Description
Novel fluorine-containing spiroacetal compound and preparation method thereof technical field The present invention relates to a bifunctional fluorine-containing spiroacetal compound that can be used as a raw material monomer for fluoropolymers having, for example, chemical resistance, weather resistance, hydrophobicity / oleophobicity, low The intermolecular interaction, low refractive index and high transmittance characteristics. The present invention also provides a method for preparing the compound. Background technique It is known that difunctional ester compounds, acid halides, and alcohol compounds can be used as monomer components for the preparation of condensation polymers. Recently, attention has been focused on fluorochemical properties such as chemical resistance, weather resistance, hydrophobicity / oleophobicity, low intermolecular interaction, low refractive index, and high transmittance, thus greatly promoting fluoropolymerization. development of things.
