Dielectric response, from 1 Hz to 10 MHz, of liquid crystalline side chain elastomers has been compared to the one of analogous uncrosslinked materials. Results are discussed in terms of mobility of the mesogens. Two different systems have been inves

In this paper, the problem of electromagnetic scattering from a 3D system of spheres is con- sidered and an iterative solution that accounts for multiple scattering is proposed. The Mie formalism used for a single sphere is extended to account for mu

A new class of side chain liquid crystalline polymers containing a polypyrrole main chain has been synthesized. These materials were shown to be promising because they combine orientational behaviour and useful electrical properties. Two chemical pro

Acetylenic and diacetylenic liquid crystalline monomers have been prepared in order to obtain conjugated polymers with an orientational character. Unlike the polydiacetylene derivatives obtained and which do not exhibit any mesomorphic behaviour, a s
