In the present invention, when preparing a polyisocyanate composition, a phenolic stabilizer is mixed at 10 to 1000 ppmw with respect to the total weight of the aromatic diisocyanate, and then a polyhydric alcohol is added to perform polymerization reaction. There is provided a method for producing a polyisocyanate composition capable of suppressing the occurrence of clouding and improving the transparency of a product. |
