View Section, Rheology of Thermoplastic Polyurethanes. Michael Cates studied physics at Cambridge University. Sir Sam Edwards. Since he holds a Royal Society Professorship. His key role in making the Edinburgh group a world-leading center in soft matter physics and rheology is well-known. His ever lasting impact on rheology is well-known to and appreciated by our community. There is no rheologist who does not know the name Cates and has not come across at least some of his papers.
His enclosed CV speaks for itself. The numbers are unmatched: Over papers, citations, an impressive h index of 65, over invited talks, several named lectures, an array of students and postdocs pursuing successful careers. In addition, he is very frequent lecturer and a very excellent one in various short courses. Manfred H. Wagner was born in Stuttgart, Germany, in After 2 years as post-doc in Polymer Physics with Prof.
He is a member of the Editorial Boards of several key rheology journals. For more than three decades, Manfred has been a prominent figure in polymer rheology.
His research has always been characterized by a quest to identify by thorough analysis, the underlying fundamentals in diverse experimental evidence, and to seek a fundamental understanding of phenomena. He has published to date over papers on rheology and processing of polymers as well as solid state physics, and carbon and graphite technology. During his PhD studies on film blowing, he became intrigued by the elongational strain hardening behavior of LDPE as first investigated by Meissner, and later by Laun and Muenstedt.
In a series of papers from to , he demonstrated that the complex nonlinear elongational and shear flow behavior of polymer melts can be reduced to two material functions, the linear-viscoelastic relaxation modulus and a nonlinear strain function. Manfred was also one of the first to consider the relevance of irreversible destruction of entanglement connectivity by deformation , a subject he and his co-workers returned to later with detailed studies on step-strain experiments By studying universal rheological aspects of polymer melts and rubbers, he gave a fundamental explanation of the origin of the C 2 term in rubber elasticity Applying his insight in rheology to polymer processing led to the concept of Rheotens mastercurves For his outstanding contributions to the science and technology of polymers, the Institute of Materials, London, awarded him the Swinburne Award in His latest contribution to constitutive modeling of polymer melts, the Molecular Stress Function MSF theory developed since , modifies the tube model of Doi and Edwards by considering the tube diameter to change with deformation.
It is particu- quantitative tools in polymer science and engineering. Rheology is distinguished from fluid dynamics be- cause it is concerned with the three traditional states of rheological properties are very sensitive to certain aspect matters rather than only liquid and gases. Rheological of structure and they are simpler to use than analytical properties have important implications in many and di- methods, such as nuclear magnetic resonance. Secondly, verse applications. Often, an additive is used to impart it is the rheological properties that govern the flow be- the desired flow behaviour.
Among these, organoclay haviour of polymers when they are processed in the mol- products, formed by the reaction of organic cations with ten state. Considering the structures of polymers by smectite clays, are the most widely used additives for means of the size and shape of molecules and the distri- solvent-based coatings. The often used cation, usually a bution of these characteristics among the molecules, quaternary ammonium salt, influences the performance structure formation and controlled assembly are the focus of the resultant organoclay.

While immiscible blend often follows predict- able rheology pattern since they exhibit single phase In the last three decades, considerable progress has been behaviour , the rheology of phase-separated system is made in the rheology of polymer solutions and polymer much more complex. Its phase morphology is a major melts.
The measurement of rheological properties of any factor, since it critically affects the size and shape polymeric material in the molten state is crucial in order changes in shear flow, as observed by viscosity. The con- to gain fundamental understanding of the processability tinuous phase of the phase-separated blend is determined of that material.
This is because rheological behaviours by two important factors, viz: the volume fraction and are strongly influenced by the material structure and the the viscosity of the components.
