REACTIVE SILSESQUIOXANE COMPOUND AND POLYMERIZABLE COMPOSITION CONTAINING AROMATIC VINYL COMPOUND

摘要

[Problem] To provide a polymerizable composition suitable for preparing a molded article that maintains a high refractive index and a low Abbe number while making it possible to minimize changes in size caused by a thermal history of high temperatures. [Solution] A polymerizable composition containing (a) 100 parts by mass of a specific reactive silsesquioxane compound, (b) 10-500 parts by mass of a specific fluorene compound, and (c) 1-100 parts by mass of a specific aromatic vinyl compound. Also provided is a cured article obtained by curing the polymerizable composition.
