Organosoluble polyimide/silica hybrid materials were prepared using the sol-gel process. The organosoluble polyimide was based on pyromellitic anhydride (PMDA) and 4,4Ј-diamino-3,3Ј-dimethyldiphenylmethane (MMDA). The silica particle size in the hybrid is increased from 100 -200 nm for the hybrid co
