Electrochemical behavior of hydroquinone and 4F-hydroquinone has been studied on Pt/polyaniline (PANI) electrodes in 1 M H 2 SO 4 solution. Redox transformation of quinone/hydroquinone systems takes place on PANI practically without overpotential and

The variation of electrical properties of the emeraldine base form of polyaniline during its transformation from a suspension in m -cresol to the dry state was studied in situ, employing electrical impedance measurements at 30 °C in a wide range of

Polypyrrole-poly(heptamethylene p,p'-bibenzoate) conducting materials, PPy-P7MB/ClO 4 , were obtained by anodic coupling of pyrrole into a polybibenzoate inert matrix, using perchlorate anions as dopant agent. P7MB is a main-chain liquid crystalline

Partial specific volumes, υ 2 -0 , of poly(D-β-hydroxybutyrate), PHB, were determined by density measurements in several chloroaliphatic hydrocarbons. We observed that υ 2 -0 of PHB in tetrachloroethane is influenced only very little by temperatur

The dipole moments of the title diketones have been measured and compared with the values calculated by MM2. Both sets of values are in good agreement. The diketones exist (74–94%) in pairs of enantiomeric conformations with angles between both car
