Abstract

Disclosed is a polythiocarbonate resin containing a repeating unit represented by the general formula (I) below, which is high in transparency, refractive index and Abbe number while being excellent in heat resistance and impact resistance. Also disclosed is an optical material using such a polythiocarbonate resin. Further disclosed is a sulfur-containing compound having an Abbe number of not less than 40 which has a high refractive index, high Abbe number, excellent transparency and excellent heat resistance, and is obtained by reacting a dithiol compound represented by the general formula (II) below with a diene compound represented by the general formula (III) below, so that it contains a repeating unit composed of a structural unit derived from the residue of the dithiol compound and a structural unit derived from the residue of the diene compound. Still further disclosed are a method for producing such a sulfur-containing compound, a sulfur-containing polymer including such a sulfur-containing compound as a constitutional unit, and an optical material containing such a polymer.
