Summary: Macromolecular Microsymposia-XII and XIII provides information pertinent to the fundamental aspects of polymers and polymer solutions. This book discusses the structures in polymer solutions and the transformations of functional groups in polymers. Organized into two parts encompassing 15 chapters, this book begins with an overview of the method for the determination of the structure of block copolymers in concentrated solution and in the dry state. This text then examines the liquid crystalline mesophases of the cholesteric type where one requirement is the existence of chiral single molecule.
