ABSTRACT:
Novel thioglycerol derivatives, processes for their manufacture, and optical materials made from such compounds. The thioglycerol derivatives have high concentrations of sulfur relative to compounds conventionally used for optical materials, and thus exhibit high refractive indices without sacrificing processability.
