Abstract

PURPOSE:To obtain the titled lens with less yellow stain, especially at the time of polymerizing, by composing the titled lens of a copolymer contg. a diallylphthalate, a diethylene glycol bisallycarbonate and a glycidylmethacrylate with a specified weight ratio. CONSTITUTION:A mixture composed of 90-20pts.wt. of diallylphthalate or diallyisophthalate, 5-40pts.wt. of diethylene glycol bisallycarbonate and 5-40pts. wt. of glycidyl methacrylate and a polymerization initiator is filled into a casting mold for the lens, and then copolymerized by heating, etc., followed by curing the molding to form the titled lens. Thus, the titled lens with good formability, transparency, dye-affinity and physico-chemical property, is obtd. and the titled lens with the less yellow stain at the time of polymerizing, and composed of the high refractive index is obtd.
