| abstract |
An organometallic polymer material is obtained which excels in translucency, shows improved hardness after it is cured and exhibits high reliability at high temperature and high humidity. n Characteristically, the organometallic polymer material contains an organometallic polymer having an -M-O-M- bond (M indicates a metal atom), a metal alkoxide having a single hydrolyzable group and/or its hydrolysate and an organic polymer having a urethane bond and a methacryloxy or acryloxy group, and preferably further contains an organic anhydride and/or an organic acid. |
