In this work, we discuss the process development and scale-up of the melt polycondensation of polyester amides from a laboratory scale to kg-scale in a kneader reactor. We identified and optimized the most important critical parameters and produced kg-quantities of polyester amides with Mn up to 25'000 g/mol and reproducible thermal and mechanical properties. The special kneader reactor allows safe and efficient scale-up of polymerisation reactions at high temperature and viscous melts due to good mixing and efficient mass transfer.
