✦ Synopsis

The catalytic activity of the [Rh(cod)Cl], complex (cod = cis, cis-cyclo-octa-1,s-diene) with respect to the polymerization of ethynylferrocene (EFc) was examined. A good yield (about 80%) of polyethynylferrocene (PEFc) was obtained in benzene by addition of sodium hydroxide as CQcatalyst. PEFc was insoluble in most organic solvents. The conductivity (a) of the undoped polymer is about lo-'' ohm-' cm-'; upon doping PEFc with iodine in tetrahydrofuran the conductivity can be increased to 10-100 ohm-' cm-'. The influence of other doping agents was also examined,

The volumetric oxygen transfer coefficient, KLa, is one of the most important parameters in the scaleup of aerobic fermentation processes. It is a measure of the gas-liquidoxygen transfer performance of a given fermentor. Because of the involvement of oxygen in the metabolic energy supply, the KLa v
