Abstract
Disclosed is a composite composition obtained by polymerizing a radical-polymerizable vinyl compound (A) in the presence of a silica polycondensate (B) formed by hydrolysis and polycondensation of at least one alkoxysilane compound in a dispersion system of colloidal silica. This composite composition has high transparency, rigidity, toughness and thermal resistance and is hence useful in applications where inorganic glass has heretofore been used.
