Curable polysilsesquioxane compound, method for producing the same, curable composition, cured product, and method of using curable composition

摘要

The present invention relates to a curable polysilsesquioxane compound having one or more structural units represented by the formula: R1SiO3 / 2 (wherein R1 represents an alkyl group having 1 to 10 carbon atoms). The 29Si nuclear magnetic resonance spectrum has a first peak top in a region of −60 ppm or more and less than −54 ppm, a second peak top in a region of −70 ppm or more and less than −61 ppm, and −53 ppm or more− A curable polysilsesquioxane compound having substantially no peak in a region of less than 45 ppm; a curable composition containing the compound and a silane coupling agent; a method for producing the curable compound; A cured product obtained by curing the composition; and a method of using the composition or the like.
