In The Crystallization of Polymers, 2nd Edition, Leo Mandelkern provides a self-contained, comprehensive and up-to-date treatment of polymer crystallization. All classes of macromolecules are included and the approach is through the basic disciplines of chemistry and physics. The book discusses the thermodynamics and physical properties that accompany the morphological and structural changes that occur when a collection of molecules of very high molecular weight are transformed from one state to another. Volume I is a presentation of the equilibrium concepts that serve as a basis for the subsequent volumes.
