ABSTRACT:
A novel organic/inorganic hybrid material has been discovered comprising a functionalized silsesquioxane and an organic component having reactive endgroups wherein the organic backbone of the organic component is selected from polyimides, polyquinoxolines, polyether ketones, polyether sulfones, and polyesters. The hybrid materials are useful as films that may be employed as reinforced plastics, lightweight metal replacements, and as coatings.
