The *Physical Properties of Polymers Handbook* is a comprehensive resource edited by James E. Mark, focusing on the physical properties of polymers relevant to physical chemistry and chemical physics. The second edition includes updates and 11 new chapters, covering novel polymer structures such as dendrimers, polyrotaxanes, foldamers, and supramolecular polymers. It also delves into reinforcing phases like carbon black, silica, clays, and carbon nanotubes, and includes experimental studies on single polymer chains. The handbook aims to provide concise and reliable information, emphasizing modern topics such as fractal dimensions, computational parameters, liquid-crystalline polymers, medical applications, biodegradability, and surface properties. Contributions were reviewed by a panel of experts to ensure quality and relevance. The editor acknowledges the support of Springer and his wife, Helen, for their contributions to the project.The *Physical Properties of Polymers Handbook* is a comprehensive resource edited by James E.
