摘要： The present invention relates to a polythiol composition that includes (a) a polythiol compound (A) having at least two thiol groups; and (b) a nitrogen-containing compound (B) represented by the following Formula (I). In Formula (I), -S-R is a residue of the polythiol compound (A). A peak area of the nitrogen containing compound (B) is equal to or less than 3.0, with respect to a peak area of 100 of the polythiol compound (A). Each peak area for compounds (A) and (B) is determined by high performance liquid chromatography analysis. The present invention also relates to a polymerizable composition that includes the polythiol composition, and polymerizates thereof.

摘要： A batch process for preparing a molded optical article includes introducing (i) a dithiol component or (ii) a polyisocyanate component into a reaction vessel; adding a first catalyst of organotin halide to form a first reaction mixture; heating the first reaction mixture; introducing a second catalyst of tertiary amine to the first reaction mixture; mixing a polyisocyanate (ii) into the reaction vessel containing the first reaction mixture if dithiol (i) was first added, or mixing a dithiol (i) into the first reaction mixture if the polyisocyanate (ii) was first added, to form a second reaction mixture; filling a mold with the second reaction mixture to provide a filled mold to form a molded optical article. The molar ratio of elemental tin present in the first catalyst to tertiary amine compound present in the second catalyst ranges from 0.04:1 to 0.29:1.
