摘要： A novel sulfur-containing compound represented by the general formula (I):
wherein n is an integer from 0 to 2; R represents a hydrogen atom, a vinyl group, a methacryloyl group, a vinylbenzyl group, a glycidyl group, an acryloyl group or an allyl group; and the case where n is 0 and R is a hydrogen atom is excluded, and a method for preparing said sulfur-containing compound. The novel sulfur-containing compound of the present invention can be copolymerized with various copolymerizable compounds to yield excellent hardened products of high refractive index. The novel sulfur-containing compound of the present invention can therefore be used as a very useful monomer for the production of optical materials, paints, adhesives, sealants, etc. having excellent properties.
