A series of functional polyhedral oligomer silsesquioxnae (POSS)/polyimide (PI) nanocomposites were prepared using a two-step approach, first, the octa(aminophenyl)silsesquioxane (OAPS)/NMP solution was mixed with polyamic acid (PAA) solution prepared by reacting 4,4′-diaminodiphenylmethane and 3,3′,4,4′-benzophenonetetracarboxylic dianhydride in NMP, and second, the polycondensation solution was...
Light scattering and viscometric measurements were made on ternary mixtures of high molecular weight polyacrylamide (PAM), and the nonionic surfactant, Triton X-100 (TX-100) in aqueous solution. The binary solutions of polymer and surfactant in aqueous media were also studied. In the ternary system, the solution viscosity and translational diffusion coefficients were determined at 30°C in terms of...
