- the typical method for producing the silsesquioxane resin involves the hydrolysis and condensation of the appropriate silanes. By this method it is possible that residual -OH and/or -OR' will remain in the silsesquioxane resin as a result of incomplete hydrolysis or condensation. If the total amount of units in the silsesquioxane resin containing -OR' groups, exceed 60 molc% then gellalion and instability of the resin may occur.
