This is the first volume which is devoted to the memory of World Renowned Scientist professor Rusanov Alexander L'vovich. This book presents current research in the study of the unique properties of polymers and composites. Topics discussed include new condensation monomers and polymers based on TNT-derivatives; the novel polynaphthylimides of improved solubility on the basis of derivatives from chloral and dichlordiphenyltrichlorethane; the synthesis and study of the polyphthalimides with lateral arimide groupings based on chloral and dichlordiphenyltrichlorethane derivatives; ferrocene-containing polyphenylenes as precursors for magnetic nanomaterials; non-conventional polymers composed of naturally occurring a-amino acids and copolymers as stabilising media for nanoparticles.
