4. Contribution of modeling

After outlining the difficulties of modeling and how it can be applied, we will illustrate its interest with a few examples of applications, limited to polymerization and chemical modification reactions. The case of polymer blends, composites or thermoplastic elastomers, for which, in addition to the chemical reaction involved, there is the essential problem of morphology evolution and control, will not be dealt with here.

4.1 Complexity of coupling

As described above, a reactive extrusion operation is a complex process, which adds to the classical difficulties of twin-screw extrusion that of controlling a chemical reaction carried out under very specific conditions. The large number of parameters that can influence the result, as well as the numerous, complex...
