FLUORINATED POLYFUNCTIONAL (METH)ACRYLIC ESTERS, FLUOROMONOMER COMPOSITION, MATERIAL WITH LOW REFRACTIVE INDEX, AND LOWLY REFLECTIVE FILM

摘要

Fluorinated polyfunctional (meth)acrylic esters represented by general formula (1), a fluoromonomer composition containing the same, a material with a low refractive index obtained by curing the monomer composition, and a lowly reflective film comprising the material with a low refractive index wherein: R?1, R2, R3, and R4¿ are the same or different and each represents hydrogen, acryloyl, or methacryloyl, provided that at least either R1 or R2 and at least either R3 or R4 represent each acryloyl or methacryloyl; and R represents C¿2-12? fluoroalkylene having two or more fluorine atoms.
