摘要：
The present invention provides a composition comprising a vinylbenzylthio compound represented by the following general formula ##STR1## in which m is an integer of 2-3, n is an integer of 1 and R is a hydrocarbon group of 3-6 carbon atoms or a hydrocarbon group of 3-6 carbon atoms containing a bivalent sulfur atom, and a monomer radical-copolymerizable with said vinylbenzylthio compound.Said composition is useful for producing a plastic lens having a high refractive index, a small specific gravity, excellent heat resistance and excellent processability.
