METHOD OF PRODUCING SULFUR-CONTAINING TRANSPARENT POLYMER

摘要

The present invention relates to a method of producing a sulfur-containing transparent polymer by polymerizing a composition containing a (metha)acrylate monomer having sulfur in its molecule, characterized by radical polymerization of a composition containing at least one compound selected from radical chain transfer compounds and radical trapping compounds in an amount of 0.1 to 7.0 % by weight of the total amount of the composition. The polymer obtained by polymerization is less colored. The method can provide a polymer having a high total light transmittance, a high refractive index and a light weight and is hardly yellowed during use.
