From the Authors Introduction Diffusion is one of the few manageable nonequilibrium pro- cesses during which matter is transported through a system. Traditionally, diffusion is studied in physical chemistry; however, the fundamental understanding of diffusion processes is not possible without involving statistical physics. Diffusion in disordered systems, such as in polymers, has sometimes unexpected features, the nature of which has not yet been determined. Since modern technology involves more and more complex materials which rely on a subtle balance of microscopic effects, the understanding of diffusion processes in these materials is of paramount importance from the practical point of view. A renewed interest in the basic principles of diffusion is a direct result of new experimental data. This was a contributing factor in the preparation of this text. In the first chapter, the phenomenological thermodynamic basics of diffusion is reviewed, and the diffusion equation is derived from the principles of irreversible thermodynamics. The basic mathematical apparatus for solving diffusion equations is reviewed in the second chapter. The third chapter deals mainly with the vast amount of experimental data dealing with diffusion in polymers. . . . A reader interested in particular polymeric systems can use the . . . material as a useful introduction. The last chapter contains basic information concerning random walks and their application to the diffusion in disordered systems. The theory of random walks is widely used in polymer physics where it is usually combined with statistical mechanics to formulate various models of polymeric systems. Finally, useful mathematical formulas and references to the original sources of some mathematical methods are [provided] in the appendices. Some physical constants associated with several polymer solvent systems are also presented.

This multi-authored book includes selected contributions reviewing the results achieved in the synthesis and characterization of organized polymeric materials. The focus is on competitive materials with liquid crystalline or electroconductive properties. The fine tuning of the properties offered by advanced chemical synthesis has been investigated by a large number of state-of-the-art techniques, including both microscopic (ESR, NMR, dielectrometry, fluorescence, IR, Raman spectroscopy) and macroscopic (calorimetric, mechanical) methodologies. The book also provides an updated coverage of the most challenging applications of organized polymers as functional materials in the fields of electrooptical devices, information retrieval and organic electroconductors.

The theories of thermal transport in polymers, which are mainly qualitative, are reviewed. The behaviour of amorphous polymers is better understood than that of partially crystalline ones. An apparatus for measuring the thermal conductivity of solid and molten polymers from room temperature to 250 degrees C is described. 'Edge effects' are eliminated by enclosing the heat source and samples inside the heat sink; hence guard rings are not used. The heat flow is three dimensional and the conductivity is obtained by a numerical calculation. Two disc shaped samples 48mm diameter and 2mm thick are required. An apparatus for measuring the thermal diffusivity of solid and molten polymers from room temperature to 250 degrees C is also described. Disc samples the same size as for the conductivity apparatus are used and the heat equation is again solved numerically. Conductivity and diffusivity results are reported for high density polyethylene, polypropylene, three grades of polymethyl methacrylate, three grades of polystyrene, and a series of carbon black filled natural rubber compounds. To show the effect of molecular weight, conductivity results for a range of polyethylene glycols and a range of silicone fluids are also presented.
