PROBLEM TO BE SOLVED: To provide a method for producing a new fluorine-containing polymerizable unsaturated monomer useful for producing a polymer compound having high transparency to the light having wavelength of ≤300 nm, especially vacuum ultraviolet rays of F2excimer laser (157 nm), or the like.
SOLUTION: The monomer expressed by formula (4) (R1is fluorine atom or a fluoroalkyl group; an adamantane thereof ring may have substituents) is produced by reacting a compound expressed by formula (1) (the adamantane ring may have substituents) with a methylation agent expressed by the formula (2): CH3-M (M is a metal atom or MgX1group (X1is a halogen atom)) and reacting the reaction product with an unsaturated acyl halide expressed by formula (3) (R1is same as defined above; and X2is a halogen atom).
