Polyimide-silica (PI-SiO 2 ) hybrids with a nanostructure was obtained using the nonaqueous sol-gel process by polycondensation of phenyltriethoxysilane in a polyamic acid solution. Self-catalyzed hydrolysis of phenyl-substituted akoxysilane and modification on the polyimide structure are applied an
Aliphatic polyimides (P-XBTA) having inherent viscosities of 0.4-1.4 dL/ g were readily synthesized by the high-pressure polycondensation of the salt monomers, composed of aliphatic diamines having various methylene chain lengths ( X Å 4-12) and 3,3,4,4-benzophenonetetracarboxylic acid (BTA), under
