POLYMERIZABLE COMPOSITION AND CURED RESIN COMPOSITION

摘要

A polymerizable composition which is significantly improved in coefficient of linear expansion, etc. while retaining intact excellent properties of norbornene resins, such as heat resistance and mechanical strength. The polymerizable composition comprises a polymerizable substance comprising a norbornene monomer or oligomer as a major component, a metathesis polymerization catalyst, and silica particles, the content by weight of the silica particles being higher than that of the polymerizable substance.
