Provided is a polymerizable composition including (meth)acrylate monomers having at least two sulfide (-S-) linkages in the monomer. The polymerizable compositions include a first (meth)acrylate monomer represented by the following Formula (I),
where L1 is selected from a multivalent optionally substituted hydrocarbyl group optionally interrupted with at least one of -C(O)-, -S-, -O- and combinations thereof, and a divalent linking group represented by the following Formula (A).
In Formula (A), Y is O or S. Also in Formula (I), L2 is independently for each n a divalent optionally substituted hydrocarbyl group optionally interrupted with at least one of -O- and -S-, R1 is independently selected for each n from hydrogen and methyl, and n is from 2 to 6. The polymerizable compositions also may include a polymerization moderator. Also provided are polymerizates including photochromic articles and optical elements prepared from such polymerizable compositions.
本发明提供了一种可聚合组合物,包括在单体中具有至少两个
硫化物(-S-)连接的(甲基)
丙烯酸酯单体。可聚合组合物包括由下式(I)代表的第一种(甲基)
丙烯酸酯单体、
其中 L1 选自至少用-C(O)-、-S-、-O-及其组合中的一种任选间断的多价任选取代的烃基,以及由下式(A)表示的二价连接基团。
在式 (A) 中,Y 是 O 或 S。同样在式 (I) 中,
L2 对于每个 n 独立地是二价任选取代的烃基,任选被 -O- 和 -S- 中的至少一种打断,R1 对于每个 n 独立地选自氢和甲基,n 是 2 到 6。可聚合组合物还可包括聚合调节剂。此外,还提供了聚合物,包括光致变色物品和由此类可聚合组合物制备的光学元件。
