The main goal of this book is to discuss various technological methods of reactive processing of polymers with a special emphasis on production of large size articles. The book also shows methods of scaling up from laboratory to production stage by a combination of process modeling and application of modern analytical techniques to evaluate the similarity of production on different scales.

This approach allows to shorten introduction of new products and design the energy efficient (environmentally-friendly) processes. The combination of physical analysis of process kinetics to elucidate data for evaluation of process similarities on different scales is very useful in setting process parameters on the most energy-efficient level and having a high production output. The proposed method allows to maximize throughput, minimize cost and ensure required quality of the final products.

This unique approach not only gives objective results required for precise evaluation of process kinetics but it is applied in the book to real systems used as examples of model application. To fulfill the above goals, the book begins with a discussion of the chemistry of reactive processes which are then discussed from the point of view of their modeling. The modeling considers that reactive processing is impacted by various opposing requirements of flow, polymerization rate, crystallization rate, heat flow, etc. This is the main advantage of the approach when used for process optimization. In the next section, analytical control methods are evaluated for their usefulness in process monitoring. The final (and the largest chapter) discusses details of various technological methods of reactive processing by means of 70 diagrams clearly discussed and thus easy to understand. This interesting monograph is addressed to process engineers and scientists developing new products since both have to optimize their processes to obtain the most economical solution. But it also goes beyond reactive processing since problems of scale-up are common in entire chemical industry and this book shows the way how to control them, introduce new processes without long trials, and design technology which is cost-efficient and environmentally-friendly. All explained in easy to understand language.
