| titleOfInvention | Manufacturing method of polymerizable composition for optical materials, manufacturing method of transparent resin, and manufacturing method of lens base material |
| abstract | The present invention provides a method for producing a polymerizable composition for an optical material, and the like, which can stably produce, with good reproducibility, thiocarbamates in which coloration is suppressed despite the use of a polyene compound and an aromatic polyisocyanate The polymerizable composition for optical materials. The method for producing a polymerizable composition for an optical material of the present invention includes the steps of preparing an aromatic polyisocyanate, a polyene compound having two or more ethylenically unsaturated double bonds, and a polythiol; A step of mixing polythiols to obtain a mixture; and a step of adding the above-mentioned aromatic polyisocyanate to the above-mentioned mixture, and mixing at least three components of the above-mentioned aromatic polyisocyanate, the above-mentioned polyene compound, and the above-mentioned polythiol. |
