Abstract
A polymerizable composition suitable for producing a molded article that can maintain a high refractive index and a low Abbe's number and can be restrained from dimensional changes due to a high-temperature thermal history has (a) 100 parts by mass of a specific reactive silsesquioxane compound, (b) 10 to 500 parts by mass of a specific fluorene compound and (c) 1 to 100 parts by mass of a specific aromatic vinyl compound. A cured product can be obtained by curing the polymerizable composition.
