(v) (83% carboxymethylation) Hence, permutations of these properties can lead to an almost infinite variety of molecules for specific and general end uses, literally at the push of a button. This rapid and effective response can serve a multitude of needs in various industries. SUMMARY A large scale, computer-generated statistical experimental design has been successfully applied to create a predictive tool for an homologous series of alkyl alkoxy methylcarboxylates. The rapid response time provided by this technique now affords the cosmetic/toiletries and household product industries with a source of surfactants of specific properties for their unique end uses.

Luthy and Chris Schouten.

Book Review RHEOMETRY: INDUSTRIAL APPLI- CATIONS, Edited by Kenneth Walters, Research Studies Press, A Division of John Wiley & Sons Ltd., Chichester, New York, Brisbane, Toronto, 1980, viii q- 418 pages. Price: $75.00 This book is the first volume of a "Materials Science Research Studies Series (Series Editor: C. R. Tottie)." It is a sequel to Walter's Rheometry and is a collection of generally well-written chap- ters by experts in different areas of rheometry. The chapters are: "Fundamen- tal Concepts" (K Walters) "Detergents" (H. A. Barnes) "Lubricants" (J. F. Hutton) "Foods" (M. Van den Temple) "Molten Polymers" (J. L. White) "Paints and Painting Inks" (J. Mewis) and '•In- dustrial Aqueous Suspensions" (K. M. Beazley). The first chapter by Walters is a good concise introduction to the fundamental concepts of Rheometry, but inclusion of diagrammatic illustrations of the various flow patterns and tabulation of the practi- cal industrial situations of significant importance would have been helpful. All chapters are quite comprehensive and provide useful illustrations and extensive references. There are a few minor incon- sistencies in the usage of symbols, termi- nologies and identifications of quantities in some of the equations. The book will be a valuable asset for industrial scientists. Incorporation of a chapter on Rheometry in the Pharmaceutical Industry would have enhanced its utility.--DR.
