    • Provided is a method for producing a molded product comprising preparing a polymerizable composition for optical materials and curing the polymerizable composition for optical materials to produce the molded product. The preparation of the polymerizable composition comprises preparing a polythiol compound containing, as a main component, one kind or two or more kinds selected from a defined group of compounds, and preparing the polymerizable composition from the polythiol compound. The preparation of the polythiol compound comprises reacting 2-mercaptoethanol with a defined epihalohydrin compound to obtain a defined compound, reacting the defined compound with sodium sulfide to obtain a defined polyalcohol compound, reacting the polyalcohol compound with thiourea in the presence of hydrogen chloride to obtain an isothiuronium salt, adding aqueous ammonia to a reaction solution containing the isothiuronium salt thereby hydrolyzing the isothiuronium salt to obtain the polythiol compound and purifying the polythiol compound with hydrochloric acid.
    • 本发明提供一种成型品的制造方法,其包括制备光学材料用聚合性组合物,使光学材料用聚合性组合物固化,制造成型品。 可聚合组合物的制备包括制备含有选自定义的一组化合物中的一种或两种以上的作为主要成分的多硫醇化合物,并由多硫醇化合物制备可聚合组合物。 多硫醇化合物的制备包括使2-巯基乙醇与定义的表卤代醇化合物反应以获得规定的化合物,使定义的化合物与硫化钠反应,得到定义的多元醇化合物,使多元醇化合物与硫脲在氯化氢存在下反应,得到 异硫脲鎓盐,向含有异硫脲鎓盐的反应溶液中加入氨水,从而水解异硫脲鎓盐,得到多硫醇化合物,并用盐酸纯化多硫醇化合物。
