Andrzej Duda is head of the Department of Polymer Chemistry at the Center of Molecular and Macromolecular Studies of the Polish Academy of Sciences in Lodz, Poland and currently chairman of the Polymer Section of the Polish Chemical Society as well as a member of the Polish National Science Center. He received his MSc degree from Lodz Univereity of Technology (1975), his PhD (1984, under the supervision of Stanislaw Penczek), and his DSc (1997) from the Polish Academy of Sciences. Since 2004, he has been a full professor in chemistry with the title conferred by the President of Republic of Poland. His research interests focus on thermodynamics, kinetics, and mechanisms of the ring-opening and ionic polymerizations, reactivity-selectivity relationships in polymerization, methods of controlled/living polymerization, macromolecular engineering, and polymers and monomers available from renewable resources. He is the author and coauthor of more than 100 scientific papers (including 5 book chapters).

Process Technology. In commercial addition and condensation polymerization processes reactor design is an important factor for the quality and economics of the polymer. Combining macromolecular kinetics with reactor and process design has led to a new concept called reaction engineering. D. C. Chappelear and R. H. M. Simon review this novel concept in Chapter 1. 

Thus chemical kinetics of polymerizations is often expected to describe the consequences of the existence of species whose concentration and structure remain unknown. On the other hand, kinetic studies reveal the existence of these species and thus provide a basis for their future analysis. The mastering of macromolecular syntheses is unthinkable without a knowledge of the corresponding process kinetics. Interest is centred on the determination of the overall polymerization rate and of the rates of individual steps, of the product molecular mass, and of the changes in these quantities induced by external conditions. Kinetic data also form the basis of the chemical engineering of polymer production. 

Water molecules are constantly in motion, even in ice. In fact, the translational and rotational mobility of water directly determines its availability. Water mobility can be measured by a number of physical methods, including NMR, dielectric relaxation, ESR, and thermal analysis (Chinachoti, 1993). The mobility of water molecules in biological systems may play an important role in a biochemical reaction s equilibrium and kinetics, formation and preservation of chemical gradients and osmotic pressure, and macromolecular conformation. In food systems, the mobility of water may influence the engineering processes — such as freezing, drying, and concentrating chemical and microbial activities, and textural attributes (Ruan and Chen, 1998).
