26th International Congress of Pure and Applied Chemistry, Volume 5: Macromolecular Chemistry is a collection of session lectures presented at the 26th International Congress of Pure and Applied Chemistry, held in Tokyo, Japan on September 4-10, 1977. This volume is divided into nine chapters and starts with an examination of the photomechanical effects in photochromic systems. The succeeding chapters deal with the synthesis and characterization of polyquinolines; the general concept of 'no catalyst alternating copolymerization; the synthesis of various condensation polymers with functional groups, such as ether, hydroxyl, epoxy; or formal groups; and the application of excited state quenching to macromolecular photostabilization. These topics are followed by discussions of the viscoelastic properties of dilute polymer solutions and the developments in the use of polymers as reactants in organic reactions. The last chapters consider the determination of the helix-coil stability constants of the naturally occurring amino acids using random copolymers. These chapters also examine the structure and dynamics of solid polymers using elastic and inelastic neutron scattering. This book will prove useful to polymer chemists, researchers, and students.
