Educational Goals

The course is aimed at teaching the fundamentals of polymer processing. In addition to the specific processing techniques used to convert raw polymeric materials into finished products, the principles of polymer melt rheology, which governs the material behaviour during the various processes, are studied.

Content

- Rheology of polymers
- Polymer processing

Extended Syllabus

- Rheology of polymers

Main parameters for the rheological description of fluids. Laminar and turbolent flows. Rheological constitutive equations. Newton's law of viscosity. Non-newtonian behaviour, with particular reference to polymer melts. Isothermal flows in ducts. Measurement of shear viscosity of polymer melts: capillary rheometer. Measurement of "melt index" of polymer melts. Viscoelastic behaviour of polymer melts. Temperature effects. PvT relationships.

- Polymer processing

Single-screw plasticating extrusion process. Compounding process. Injection moulding process. An outline of: blow moulding process, rotational moulding process, thermoforming. Residence time distribution functions.
