Malvern downloadable presentations guide best practice in rheology measurement
A range of “on-demand” presentations on the Malvern instruments web site provides expert guidance for analysts involved in making rheology measurements. These include “best measurement practice for capillary rheology”, and guides for making dynamic or oscillatory measurements on a rotational rheometer, focusing on “good measurement practice” and“avoiding measurement artefacts”.
“Best measurement practice for capillary rheology” provides tips and guidance to ensure precise, accurate testing every time, from sample loading to basic instrument control through to more advanced measurement options.
For dynamic or oscillatory measurements on a rotational rheometer, “good measurement practice” deals with ways of increasing the confidence you have in your oscillatory measurements by explaining some methods of good practice, in particular, the linear viscoelastic region and its importance, and stress vs strain oscillation. A separate presentation “avoiding measurement artefacts” discusses ways of minimizing errors and obtaining reliable data.
Also available are a basic introduction to rheology and presentations illustrating the link between rheology and particle properties, such as size distribution, shape and zeta potential.

PVC Degradation and Stabilization
Author: George WypychISBN 978-1-895198-39-3Published: 2008Second editionPages: 442Figures: 275Tables: 66
With the global renewal of interest in PVC, this book is well timed,considering that PVC stabilization is the most important aspect of its formulation and performance.
Only four books have been published on PVC degradation and stabilization (the last one in the 1980s), and two of them are by the author of this book.
Separate chapters review information on chemical structure, PVC manufacturing technology, morphology, degradation by thermal energy, and UV, gamma, and other forms of radiation, mechanodegradation, chemical degradation, analytic methods used in studying of degradative and stabilization processes, stabilization, and effect of PVC and its additives on health, safety and environment.
This book contains analysis of all essential papers published until recently on the above subject. It either locates the answers to relevant questions and offers solutions or gives references in which such answers can be found.
PVC Degradation and Stabilization is must have for chemists,engineers, scientists, university teachers and students, designers, material scientists, environmental chemists, and lawyers who work with polyvinyl chloride and its additives or have any interest in these products. This book is the one authoritative source on the subject.
Preface
PVC has a long history of development which began nearly 100 years ago with the patenting of the concepts of emulsion and suspension polymerization, the development of the industrial process of vinyl chloride synthesis, and patents on its plasticization, followed by the development of stabilization about 75 years ago. PVC has known rapid growth to utmost prominence and dramatic downfall almost to elimination, and it finally has regained a deserved, second position among commercial polymers.
PVC owes both its prominence and its downfall to research: meticulous,cutting-edge studies and unscrupulous bad science which stops progress and derails achievements.
PVC degradation during processing and use was always one of the most essential elements of PVC science and technology. Many approaches to stabilization changed and some groups of stabilizers are not used in new production. This book was written to show new trends and directions. It also contains clearly indicated information about past stabilizers, which is needed in order to understand the principles of stabilization and effective recycling.
For me, it has been an interesting experience to actively participate in the growth of this branch of science and summarize its achievements and the directions which it faces now, here and in my two previous books, written 25 years ago. I hope the clarity and completeness of the description of research findings as we know them today will help in further research and, most importantly, lead to successful and responsible practical applications of additives in PVC processing and applications.
