Samenvatting:

The theory presented in this book explains in a consistent manner all dynamics effects observed in very concentrated solutions and melts of linear polymers from a macromolecular point of view. The presentation is compact and self-contained.

The theory presented in this book explains in a consistent manner all dynamic effects (diffusion, neutron scattering, viscoelasticity, optical birefringence) observed in very concentrated solutions and melts of linear polymers from a macromolecular point of view. This monograph reconciles different approaches to polymer dynamics and reflects the modern situation in understanding the relaxation behaviour of the polymer systems. The reader is invited to follow the way from dynamics of a separate macromolecule to the constitutive relations for both weakly and strongly entangled linear polymers. The contents can be related to the fields of molecular physics, fluid mechanics, polymer physics and materials science. This text provides material for one or two semester graduate-level course in polymer dynamics or for graduate students with some background in physics and mathematics. The monograph presents topics in a self-contained way that makes it a suitable reference book for professional researchers in the fields of polymer science, polymer engineering, and materials science.

I used the opportunity of this edition to correct some minor mistakes and clarify, wherever it possible, exposition of the theory in comparison with the previous edition of this book (Kluwer, Dordrechtet cet, 2000). It provokes - largement of the book, though I tried to present the modern theory of thermic motion of long macromolecules in compact form. I have tried to accumulate the common heritage and to take into account di?erent approaches in the theory of dynamics of linear polymers, at least, to understand and make clear the importance of various ideas for explanation of relaxation phenomena in linear polymers, to present recent development in the ?eld. The theory of non-equilibrium phenomena in polymer systems is based on the fundamental principles of statistical physics. However, the peculiarities of thestructureandthebehaviourofthesystemsnecessitatetheimplementation of special methods and heuristic models that are di?erent from those for gases and solids, so that polymer dynamics has appeared to be a special branch of physicsnow. Themonographcontainsdiscussionsofthemainprinciplesofthe theoryof slowrelaxationphenomena in linearpolymers, elaborated inthe last decades. The basic model of a macromolecule, which allows us a consistent explanation of di?erent relaxation phenomena (di?usion, neutron scattering, viscoelasticity, optical birefringence), remains to be a coarse-grained or be- spring model, considered in di?erent environments: viscous, to describe the behaviourofdilutesolutions,orviscoelastic,todescribethebehaviourofboth weakly and strongly entangled systems.
