摘要：
A high refractive lens of a terpolymer produced by the polymerization of ternary monomers comprising diethylene glycol bisallyl carbonate, triallylisocyanurate, and benzyl methacrylate. This lens is considerably improved in its physical properties necessary for lens such as superficial hardness, transmittance, and adhesion strength of glass film coated on the surface, as well as having a high refractive index.
