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.
一种具有高折射率的聚合物是通过聚合尿烷化丙烯酸或甲基丙烯酸单体而获得的,这种单体是由具有核-卤代芳香环和羟基的丙烯酸或甲基丙烯酸单体的羟基与多官能异氰酸酯的异氰酸酯基反应而获得的。这种聚合物可作为塑料镜片的树脂材料。
