19th Discussion Conference on Rheology of Polymer Systems,

19-22 July 1999
Prague, Czech Republic

This conference was the 58th meeting in the series of Prague Meetings on Macromolecules, organized by the Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic under the auspices of the IUPAC Macromolecular Division. The aim of the conference was to provide a discussion forum for experts in the field of polymer rheology, with special emphasis on a structural understanding of macroscopic phenomena of multiphase systems.

The program committee, with Dr. Ivan Fortelen´┐Ż as Conference Chairman, succeeded in arranging a very interesting scientific program with many prominent speakers. Attendees included 73 participants from 23 countries. The topics of the conference were covered in 6 main lectures, 70 special lectures, and 27 poster contributions. In addition, two panel discussions were organized on problems of rheometry and processing in multiphase polymer systems (discussion leader: A. Ya. Malkin, Russia) and problems of the description of structure formation and evolution in molten multiphase polymer systems (discussion leader: J. Lyngae-Jørgensen, Denmark).

Main lectures included the following: "Quantitative predictions of the viscoelasticity of polymer melts" (R. G. Larson, USA), "Wall slip of polymer melts-measurement and industrial relevance" (H. M. Laun, Germany), "Some unusual rheology-morphology relationships in polymer blends" (V. G. Kulichikhin, Russia), "Long-time relaxations in rubber-modified polymer systems" (Y. Aoki, Japan), "Rheology of immiscible blends: relations to structure" (J. Mewis, Belgium), and "Rheology of reactive polymer blends" (A. Muller, France).

The meeting was well organized, and the program was conducted in a smooth and efficient manner. There were sufficient opportunities for vivid and fruitful discussions. In addition to the scientific program, the participants enjoyed a welcoming reception, an interesting excursion to historic places in the surroundings of Prague, and a splendid conference dinner.

Both the main lectures and special lectures will be published as a volume of Macromolecular Symposia.
