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.
本发明提供了一种含硫基的(甲基)丙烯酸酯化合物,每种化合物由以下式子(1)表示;其中,R1和R2各自独立地表示氢原子或烷基或可融合形成环,R3表示氢原子或甲基,X1表示氧原子或硫原子,m代表0到3的整数,n代表1到4的整数,包括含有这些含硫基(甲基)丙烯酸的可聚合组合物,以及通过聚合这些可聚合组合物获得的固化产品和光学零件。本发明中的含硫基(甲基)丙烯酸酯化合物非常有用,作为光固化、可聚合组合物的单体,在光学材料和牙科材料等应用中。通过聚合可聚合组合物获得的光学零件在光学性能、热性能和机械性能方面均优异,并且生产效率也很高。
