Ring-forming Polymerizations, Part A: Carbocyclic and Metallorganic Rings covers polymerization reactions that form carbocyclic rings and those that lead to metallorganic ring-containing structures. This book is organized into 11 chapters. The first four chapters describe ring-forming polymerizations that lead to the formation of homocyclic carbon-containing rings. These chapters specifically examine Diels-Alder polymerizations and certain diisopropenyl monomers polymerization yielding high molecular weight polyindanes. Chapter V is an introduction to polymers from metals and unsaturated carbon compounds, which has been called a "natural coordination polymer". Chapters VI to X deal with metallorganic ring polymers formed by chelation and are arranged according to the elements in the ligands that are affecting chelation. The final chapter explores ring forming polymerizations that yield polysiloxanes, polysilazanes, and certain polymetalloxanes. This book will be of value to organic chemists and researchers, as well as to organic chemistry teachers and students.
