Don Plazek
1995 Bingham Medalist

The Bingham Medal for 1995 will be awarded to Professor Don Plazek of the University of Pittsburgh. This award has been given in recognition of outstanding scientific contributions to the field of rheology, especially the measurement of polymer viscoelasticity and its relation to molecular structure.

Plazek received his Batchelors Degree in Chemistry and Ph.D. in Physical Chemistry from the University of Wisconsin. In 1967 he was appointed Associate Professor in the Metallurgical and Materials Engineering Department at the University of Pittsburgh. He attained the rank of Professor in 1975 and remained there until his retirement in 1994. From 1987 to 1994, he also served as an adjunct Professor in the Chemistry Department at Carnegie Mellon University.

Much of Professor Plazek’s early experimental work dealt with the measurement of elongational and volume creep. This resulted in improved computer methods for converting the measured creep data to other viscoelastic functions, such as dynamic modulus, as well as useful new approximation calculations. In the early 1980’s, he turned his attention to the viscoelsticity of polymers and organic glasses and made many important contributions.

Several of Plazek’s accomplishments which exemplify his ingenuity and versatility are:

  1. Accurate measurements of high reliability of viscoelastic and other physical properties of carefully characterized polymers and assembly of a mass of definitive standard viscoelastic data useful for many applications, especially for critical testing of theories of polymer dynamics.
  2. Keen observation of important relationships, which might have gone unnoticed but for the accuracy of his measurements, and discerning analysis of these results to elucidate their physical and molecular origin.
  3. Basic scientific analysis of rheological phenomena which have important applications to the processing and performance of polymer materials.
  4. Lucid exposition of the basic principles of viscoelasticity and its relation to molecular structure, illustrated by his own measurements, in review articles and short courses.

Professor Plazek received the George Stafford Whitby Award of the American Chemical Society Rubber Division in 1993 and has over one hundred publications to his name.

1995 Journal of Rheology Publication Award

The 1995 Journal of Rheology Publication Award has gone to Tom Annable, Richard Buscall, Rammile Ettelaie and Diane Whittlestone of the ICI Corporate Colloid Science Group in the UK. The award has been given for their paper entitled, "The Rheology of Solutions of Associating Polymers: Comparison of Experimental Behavior with Transient Network Theory," and published in the Journal of Rheology, 37, 695-726 (1993).

This paper gives a detailed and complete study of a very significant class of associative thickeners which function by forming transient 3-D networks. The publication presents experimental characterization of the dynamic network properties, the statistical mechanical modeling of the polymer chain configurations and a Monte Carlo simulation of the same. According to one of the reviewers, "Some of the experimental data, including dynamic moduli of blends, are quite new and exciting. Their interpretation in the light of recent transient network theory is also very interesting and will create a new world in the study of associating polymers."

Comments from the President - Bob Armstrong

I am pleased to announce that Mort Denn has agreed to serve as the next Editor of the Journal of Rheology. We are very fortunate that Mort is willing to take on this important role for the Society, as he brings to the position not only considerable stature as a rheologist with broad interests and high standards but also valuable experience as a past Editor of the AIChE Journal. Mort was the first choice of a Search Committee consisting of Bob Mendelson (chair), Bill Russel and Henning Winter, and was asked to serve as Editor by vote of the Executive Committee. I would like to take this opportunity to thank this Search Committee for a very careful and thoughtful job. Mort will serve as Interim Editor until the next election.

Of course, Mort replaces Art Metzner, who has served as Editor for the past eleven years. It is not possible adequately to express here my appreciation and high regards for the way Art handled the job as Editor. There is no doubt that he has put an incredible amount of personal energy and enthusiasm into making the Journal the premiere publication in the field of rheology, and the Society as a whole is the beneficiary of his hard work. During his tenure as Editor, the Journal has undergone great changes: we have switched publishers from Wiley to AIP in order to increase the size of the Journal, the turnaround on papers has become as short as possible consistent with quality reviewing, impartial ratings of the Journal put us ahead of or on par with the most prestigious publications, page charges have been dropped, and most importantly the quality of the papers in the Journal is exceptional. Finally, Art has worked very hard to ensure a smooth transition to the new Editor. I hope that you will all take the chance to thank Art for his enormous service to the Society. His insight and advice will also be missed by the Executive Committee.

I would like to thank Albert Co and Chris Petrie for volunteering to organize a home page on the World Wide Web for the Society of Rheology. We expect to have an initial version of the home page up and running by the end of the summer. Feel free to pass your suggestions on to Albert (albertco@maine.maine.edu) or Chris (chris.petrie@newcastle.ac.uk) or to me (rca@mit.edu).

Student-Member Travel Grants
Available for Sacramento

The Society of Rheology is again offering grants to support the cost of public transportation to the annual meeting to any second or third year graduate student who is a member of the Society as of July 1, 1995, and whose faculty advisor is also a member as of that date. Each grant will be a maximum of $350, available on a first-come, first-served basis, until available funds are exhausted. To apply, the student should write a letter requesting the grant. The student’s faculty advisor should add a letter of support, certifying that both the advisor and the student are members of the Society of Rheology, and that the student is a second or third year graduate student. Only one application per faculty advisor will be accepted. The letters from the student and the advisor should be mailed in the same envelope before September 1, 1995 to:
