    • An anhydride functional silsesquioxane resin composition containing the units: (R13SiO1/2)a  (i) (R22SiO2/2)b  (ii) (R3SiO3/2)c and  (iii) (SiO4/2)d.  (iv) R1, R2, and R3 can be an anhydride group, a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, or an alkaryl group. a is 0.1-0.6, b is zero to 0.5, c is 0.3-0.8, d is zero to 0.3, and the sum of a, b, c, and d, is one. The composition contains more than two anhydride groups. The anhydride functional silsesquioxane resin can be used to form curable one-part composition containing the anhydride functional silsesquioxane resin composition, an epoxy resin; and optionally, an anhydride containing organic curing agent, a cure accelerator, and a filler.
