Title: Sulfur-containing compounds for optical grade polymeric casting compositions

Abstract: Polymeric compositions for the preparation of optical grade materials, and the optical materials prepared thereby, are provided. The compositions include a class of reactive and non-reactive additives, referred to as additive, in combination with a polymer and optionally a diluent. The additives are preferably the reaction product of a thiol containing compound and an unsaturated compound. The additives optimally have a refractive index between about 1.40 and 1.70, and preferably between 1.50 and 1.70; a relatively high Abbe number (between 25 and 60) and minimal color.
