This course aims to give the student a thorough introduction in polymer rheology and polymer processing technology, discussing how the polymer material properties may affect or even limit the processing, as well as how the processing affects the final material properties.
First, the course focuses on the rheology of polymers and how it affects and is affected by their processing. The principles of viscous and viscoelastic flow behaviour are introduced for both shear and extensional flow, and the fundamental flow regimes, their origin, and their link to the macromolecular architecture are discussed. Experimental approaches to measure the rheology of polymer solutions and polymer melts are described, as well as approaches to model them.
Next, the processing of both thermosets, blends and thermoplastics are discussed. For thermosets, the link between the advancing polymerization and the changing rheology is explained for both step and chain growth crosslinking polymerizations, including the technological consequences of gelation and vitrification. The use of rheological and thermal analysis techniques for studying thermoset curing is discussed and illustrated in the lab sessions. In the context of the processing of polymer blends, phase separation, mixing and phase morphologies are discussed, as well as how the blend morphology can be affected during processing.
For thermoplastics, first polymer extrusion is discussed, as it is one of the most used polymer processing methods. This includes estimating the operation point of an extruder and how it is affected by the processing conditions and the visco-elastic behaviour of polymers. Next, the course focuses on injection moulding. Both its fundamental principles and practical issues and solutions are discussed. For the different stages of the process, the link is made between, on the one hand, non-Newtonian flow behaviours, heat transfer and crystallization kinetics, and the PVT diagram, and on the other hand, cosmetic issues, weld lines, flash, residual stresses and warpage.
Rubber technology or alternative topics may be introduced by speakers from industry (seminars).
Course notes via CANVAS
Knowledge and understanding of polymer rheology, polymer processing and polymeric materials' properties by means of a systematic study of ‘processing-(structure)-property relations’ (theory). Application of this knowledge and understanding to rheometrical material problems (practicals).
In the ‘Master of applied sciences and engineering: chemistry and materials’ this course is a contribution to the integrated philosophy of chemical technology and material science, in this case polymer processing and its link with macroscopic, technological polymer properties. The acquired competences are complementary to those of the course ‘Polymers: rheology and processing’.
The theory and the practicals are lectured in English. The student should communicate in English by preference, improving the student’s internationalization.
