✦ Synopsis

It was found that the electrochemical reduction of poly (tetrafluoroethylene) with lithium amalgam leading to the mixture of polymeric carbon and lithium fluoride as solid product is followed by a consecutive electrochemical reaction viaa polymeric anion radical, [fC"+ -In. The value of n was determined as 4.75 and was found to be independent of the reaction conditions. The charge of this radical is during the reaction neutralised with Li* ions diffusing through the solid phase to form a chemical compoundfC,Li), whose C-Li bonds have a localized character. Therefore, this compound does not evolve hydrogen in contact with water as the intercalation compounds C.Li, but hydrolyses to a solid hydrocarbon+Cfij,.

The viscosities of polydimethylsiloxane (PDMS)/CO 2 solutions were measured over the range of pressures of 1-3 MPa and at the ambient temperature. The viscosities were measured by using a specially designed falling ball viscometer (FBV). The Stokes equation was used to determine the viscosities and

The methods of electron microscopy and X-ray scattering were used in the investigation of the structure of carbon JADO, prepared by the electrochemical reduction of polytetrafhroroethylene, and of the intermediate system C-LiF. The carbon JAW was found to be nongraphitic with a typical nodular morph
