A polymer having a high refractive index is obtained by polymerizing a urethanized acrylic or methacrylic monomer obtained by reacting the hydroxyl group of an acrylic or methacrylic monomer having a nucleus-halogen-substituted aromatic ring and a hydroxyl group with the isocyanate group of a polyfunctional isocyanate. This polymer is valuable as a resin material for a plastic lens.
