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.
