<p>A composition comprising a thermoplastic norbornene resin and, dispersed therein, particles of an inorganic filler coated with a silane compound comprising a silicon atom and, bonded thereto, four groups consisting of one or more alkyl groups and one or more hydrolyzable groups, such as trimethoxy-p-propylphenylsilane. The composition is excellent in tensile properties and impact resistance, has such a low coefficient of linear expansion as to be excellent in dimensional accuracy resistant to temperatue changes, and is excellent in moldability to give moldings having excellent surface accuracy.</p> |
