ABSTRACT:
Disclosed is a fluorine-containing polymerizable monomer represented by the formula [1] below. (In the formula, A represents a single bond, an oxygen atom, a sulfur atom, CO, CH2, SO, SO2, C(CH3)2, NHCO, C(CF3)2, a phenyl or an alicyclic ring; a and b independently represent an integer of 0-2; and 1≦a+b≦4.) Such a fluorine-containing polymerizable monomer can be used as an effective polymerizable monomer exhibiting water repellency, oil repellency, low water absorbency, heat resistance, weather resistance, corrosion resistance, transparency, photosensitivity, low refractive index, low dielectric properties and the like. Consequently, the fluorine-containing polymerizable monomer can be applied to the field of advanced polymer materials.
