Polymer science is growing day by day. All branches of chemistry include polymers reactions. This book includes synthesis, kinetics, classification and applications. Most topics, wording and material are easy to understand and pick up the concept. The bio polymers and their types are explained with figures. Kinetics chapter includes the cationic, anionic and free radical polymerization processes. The molecular weight of polymers determination is also discussed. I hope this book will be a new initiative for beginners of polymer concept.
