The present invention provides a polythiocarbonate resin containing a repeating unit represented by the following general formula (1), having high transparency, refractive index, and Abbe number and excellent heat resistance and impact resistance, and an optical material using the polythiocarbonate resin.
Further, the present invention provides a sulfur-containing compound having an Abbe number of 40 or more, a high refractive index, a high Abbe number, excellent transparency, excellent heat resistance, and the like, obtained by reacting a dithiol compound represented by the following general formula (II) and a diene compound represented by the following general formula (III), and thus containing a repeating unit formed of a structural unit derived from a residue of the dithiol compound and a structural unit derived from a residue of the diene compound. Still further, the present invention provides a method of producing the sulfur-containing compound, a sulfur-containing polymer including the sulfur-containing compound as a constitutional component, and an optical material containing the sulfur-containing polymer.
