Media pH can affect polymer degradation, either directly, by altering the polymer chemistry involved during degradation, or indirectly, by interacting with degradation products and affecting consequent kinetics. Chu 55 found there was a greater loss in the mechanical properties of PGA sutures in buffered than unbuffered solutions. Additional Physical Format: Online version: Grassie, Norman. Chemistry of high polymer degradation processes. New York, Interscience Publishers, COVID Resources. Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle coronavirus. Photochemical Processes in Polymer Chemistry-2 contains invited lectures presented at the Second IUPAC Symposium on Photochemical Processes in Polymer Chemistry held at Leuven, Belgium on June , This book contains 11 papers separated as chapters.

The most common types of degradation occur through chemical reactions, but there are a few important examples of degradation resulting only from physical changes. This latter type of degradation results from disruption of polymer morphology, rather than reactions at the molecular level. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances. Radiation of various kinds is used to initiate many of these modern technological processes so that polymer photochemistry has come to a new prominence. However, the broadly distributed energies in the plasma exceed partially the binding energies in polymers, thus initiating very often unselective reactions and polymer degradation. The intention of this book is to present new plasma processes and new plasma reactions of high selectivity and high yield. This book aims to bridge classical and Reviews: 1. Professor Lampe was a physical chemist whose polymer interests were in the areas of radiation-induced polymerizations, kinetics of polymerization processes, application of mass spectrometry to polymer degradation processes, statistical mechanics, and molecular weight by:

Polymer Science. This book explains the following topics: Polymers and the Environment, Emulsion Polymerization, Polymer Science Approach to Physico-Chemical Characterization and Processing of Pulse Seeds, Polymer Characterization with the Atomic Force Microscope, Nonconventional Method of Polymer Patterning, The Properties and Application of Carbon Nanostructures, Electrokinetic Potential .   The intention of this book is to present new plasma processes and new plasma reactions of high selectivity and high yield. This book aims to bridge classical and plasma chemistry, particularly focusing on polymer chemistry in the bulk and on the surface under plasma exposure. The stability of surface functionalization and the qualitative and. Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the. Where earlier editions covered organic polymer chemistry, the third edition covers both physical and organic chemistry. Thus kinetics and thermodynamics of polymerization reactions are discussed. This textbook also covers such hot topics as photonic polymers, electricity conducting polymers, polymeric materials for immobilization of reagents.
