In the first part the processes, involved in the crude refining or hydrocarbon conversion into chemicals or monomers, are described through the analysis of the thermodynamic, kinetic and technological aspects of each transformations step. The second part of the course deals with the principles of industrial production of polymers and with the product characterization. The fundamentals, for step and chain reactions of polymer formation, are illustrated together with the industrial technologies developed to produce thermoplastic, thermosetting or elastomeric materials.
