A curable composition containing an inorganic compound A having sulfur atom and/or selenium atom, a compound B represented by the following formula 1:
wherein m is an integer from 0 to 4, and n is an integer from 0 to 2, and a compound C selected from the group consisting of thiol compounds having one SH group and disulfide compounds which are other than the compound B and have one or more disulfide linkages. The inorganic compound A is contained in an amount from 1 to 50 parts by weight and the compound B is contained in an amount from 50 to 99 parts by weight when a total of the inorganic compound A and the compound B is taken as 100 parts by weight. The compound C is contained in an amount from 1 to 20 parts by weight based on 100 parts by weight in total of the inorganic compound A and the compound B. The curable composition causes little increase in the viscosity even when subjected to prepolymerization and deaeration, thereby facilitating the operation of cast polymerization for producing optical materials, etc.
一种可固化组合物,含有一种具有硫原子和/或硒原子的无机化合物 A,一种由下式 1 表示的化合物 B:
其中 m 为 0 至 4 的整数,n 为 0 至 2 的整数,以及选自具有一个 SH 基团的硫醇化合物和二硫化合 物的化合物 C,该化合物与化合物 B 不同,具有一个或多个二硫键。无机化合物 A 的含量为 1 至 50 份(按重量计),化合物 B 的含量为 50 至 99 份(按重量计),当无机化合物 A 和化合物 B 的总量为 100 份(按重量计)时。以无机化合物 A 和化合物 B 的总重量为 100 重量份计,化合物 C 的含量为 1 至 20 重量份。该可固化组合物即使在进行预聚合和脱气时,粘度也几乎不会增加,因此有利于生产光学材料等的浇铸聚合操作。
