Abstract
Cast silicone compositions with high transparency suitable for use as optical components contain a base polymer with a refractive index ≥1.42, and a reinforcing particulate silica which is surface modified to have a refractive index within 0.03 of the refractive index of the base polymer, by reaction with an aryl-silane or aryl-siloxane.
