| 摘要 |
The present invention is a curable polysilsesquioxane compound comprising at least one structural unit represented by CHR 1 X 0 -D-SiO 3/2 ,
the curable polysilsesquioxane compound having a 29 Si nuclear magnetic resonance spectrum that has a first peak top within a range of -73 ppm or more and less than -65 ppm, has a second peak top within a range of -82 ppm or more and less than -73 ppm, and substantially does not have a peak within a range of -65 ppm or more and less than -55 ppm, and
a method for producing the curable polysilsesquioxane compound, and
a curable composition comprising the curable polysilsesquioxane compound and a silane coupling agent, and
a cured product obtained by heating the curable composition, and
a method for using the curable polysilsesquioxane compound or the curable composition , as an optical device-securing material. |
