This invention provides a sulfur-containing (thio)ether (co)polymer comprising repetitive structural units represented by general formulas 1 and 2, and an optical element using the (co)polymer:
where A and B are bivalent organic group; R1 and R2 are hydrogen or alkyl; X1 to X4 are oxygen or sulfur; Y1 and Y2 are halogen, hydroxy, -OR3 or -SR4, in which R3 is sulfur-containing alkyl, aryl, heterocycle or acyl optionally having a substituent other than SH; and R4 is alkyl, aryl, heterocycle or acyl; provided that -OR3 and/or -SR4 constitute 10 to 100 % of the total of Y1 + Y2. The (co)polymer exhibits good optical, mechanical and thermal properties and a higher refractive index, and may be prepared in a good productivity. The sulfur-containing (thio)ether (co)polymer is useful for manufacturing a variety of optical elements.
