OPTICAL LENS COMPRISING AROMATIC-ALIPHATIC POLYCARBONATE RESIN

摘要

The purpose of the present invention is to provide an optical lens which comprises an aromatic-aliphatic polycarbonate resin that has a large Abbe number and combines practically sufficient heat resistance with high molding flowability. This optical lens comprises a polycarbonate resin characterized in that the polycarbonate resin comprises constituent units (I) represented by formula (I) and constituent units (II) represented by formula (II), the proportion of the constituent units (II) to the sum of the constituent units (I) and (II) being 55-35 mol%, and that a solution obtained by dissolving 0.7 g of the polycarbonate resin in 100 mL of methylene chloride has a specific viscosity measured at 20ºC of 0.12-0.298.
