    • 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.
    • 本发明提供了各自由下式(1)表示的含硫(甲基)丙烯酸酯化合物,其中R 1和R 2各自独立地表示氢原子或烷基,或者可以一起稠合形成环,R 3 表示氢原子或甲基,X1表示氧原子或硫原子,m表示0〜3的整数,n表示1〜4的整数,包含含硫( 甲基)丙烯酸,以及通过聚合可聚合组合物获得的固化产物和光学部件。 作为本发明的含硫(甲基)丙烯酸酯化合物,作为光固化性聚合性组合物的单体,在光学材料和牙科用材料等应用中是非常有用的。 通过固化可聚合组合物获得的光学部件的光学性能,热性能和机械性能优异,并且生产率也良好。
