Abstract
A polymer composition having an iodine value of no less than 0.1 and no more than 0.55 is obtained by adding a light stabilizer such as N,N′-bis-(2,2,6,6-tetramethyl-4-piperidinyl)-N,N′-bis-formyl-hexamethylenediamine and an antioxidant such as 2-[1-(2-hydroxy-3,5-di-t-pentylphenyl)ethyl]-4,6-di-t-pentylphenyl acrylate to an alicyclic structure-containing polymer having a low iodine value; and an optical molded body having an iodine value of no less than 0.1 and no more than 0.6 is obtained by molding this polymer composition containing an alicyclic structure-containing polymer and a light stabilizer and/or an antioxidant.
