The main focus in this monograph is on models of the kinetics of photo-initiated polymerization of mono- and bi-functional monomers up to the high conversion stage, their derivation, analysis and comparison with the experimental data. This monograph can be useful for scientists, engineers, post-graduate training students and students who are interested in problems both of the polymerization kinetics and general chemical kinetics.

Conformation is statistical property of the macromolecules consisting of a number of N structural units, links, position of which in a space one relatively to other is not inflexibly fixed by chemical bonds and assumes the possible random configurations. The number of possible configurations at N ” 1 is so great that permits to use the statistical methods at their analysis. That is why the conformation is a result of statistical averaging on all possible configurations of the macromolecule. It was for a long time notified and confirmed by computer modelling that the conformation of polymeric chain should be described by self-avoiding random walks statistics (SARW) but not Gaussian random walks statistics, assuming the phantom behaviour of polymeric chains. Nevertheless, Gaussian statistics is dominating at the analysis of thermodynamic, dynamic and kinetic stainings of the macromolecules conformation. This book will be useful for scientists who are engaged in the physical chemistry of polymers and their solutions.

Polymers are substances containing a large number of structural units joined by the same type of linkage. These substances often form into a chain-like structure. Starch, cellulose, and rubber all possess polymeric properties. Today, the polymer industry has grown to be larger than the aluminium, copper and steel industries combined. Polymers already have a range of applications that far exceeds that of any other class of material available to man. Current applications extend from adhesives, coatings, foams, and packaging materials to textile and industrial fibres, elastomers, and structural plastics. Polymers are also used for most composites, electronic devices, biomedical devices, optical devices, and precursors for many newly developed high-tech ceramics. This new volume presents leading-edge research in this rapidly-changing and evolving field.

This collection examines the influence of liquid and solid states during radical, ionic, and molecular reactions, specifically how cage effect, diffusion hindrance, donor-acceptor interaction, electrostatic interaction, dispersion forces and other factors affect the rates, mechanism, and direction of chemical reactions. Topics of the 11 papers include spherical hydrogel particles for endovascular embolisation, the synthesis and thermal degradation of phenolic resins, mono-molecular chain termination in dimethacrylate postpolymerisation, and calculating the effect of chain deformation on macromolecule scission. Most of the researchers work in Russia.

This volume deals with chemistry of polyelectrolytes, namely biocide guanidine containing polymers, discussing both synthesis of new guanidine containing monomers of diallyl and acrylic nature and their structure and investigation of their radical (co)polymerization and properties of new (co)polymers.The first parts of the book describe radical pol
