    摘要： This invention provides sulfur-containing (meth)acrylic ester compounds each of which is represented by the following formula (1); wherein R1 and R2 each independently represent a hydrogen atom or an alkyl group or may be fused together to form a ring, R3 represents a hydrogen atom or a methyl group, X1 represents an oxygen atom or a sulfur atom, m stands for an integer of from 0 to 3, and n stands for an integer of from 1 to 4, polymerizable compositions comprising the sulfur-containing (meth)acrylic acids, and cured products and optical parts obtained by polymerizing the polymerizable compositions. The sulfur-containing (meth)acrylic ester compounds according to the present invention are very useful, as monomers for photocurable, polymerizable compositions, in applications such as optical materials and dental materials. The optical parts obtained by curing the polymerizable compositions are excellent in optical properties, thermal properties and mechanical properties and are also good in productivity.

    摘要： 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.
