Method for producing photochromic optical material |
| abstract |
The method for producing a photochromic optical material of the present invention comprises at least one type of polymerizable monomer (A) having two or more ethylenically unsaturated groups and at least one type of polythiol having two or more mercapto groups ( B) is reacted to obtain a prepolymer (i), the prepolymer and the photochromic compound (C) are mixed to obtain a polymerizable composition (ii), and the polymerizable composition And (iii) polymerizing In the step (i), the number of moles of the mercapto group of the polythiol (B) is less than the number of moles of the ethylenically unsaturated group of the polymerizable monomer (A). |
