Discusses various technological methods of reactive processing of polymers with a special emphasis on production of large size articles. 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 similarity of production on different scales. This 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. The book begins with a discussion of the chemistry of reactive processes that are then discussed from the point of view of their modeling. In the next section, analytical control methods are evaluated for their usefulness in process monitoring. The final chapter discusses details of various technological methods of reactive processing by means of 70 diagrams. It also describes how to control and introduce new processes without long trials, and design technology that is cost-efficient and environmentally friendly.
