    摘要: 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; R 1 and R 2 are hydrogen or alkyl; X 1 to X 4 are oxygen or sulfur; Y 1 and Y 2 are halogen, hydroxy, -OR 3 or -SR 4 , in which R 3 is sulfur-containing alkyl, aryl, heterocycle or acyl optionally having a substituent other than SH; and R 4 is alkyl, aryl, heterocycle or acyl; provided that -OR 3 and/or -SR 4 constitute 10 to 100 % of the total of Y 1 + Y 2 . 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.
