Learning outcomes
The course provides notions on the correlations between chemical, mechanical and thermal behaviour of macromolecules and their structure and microstructure. The complete life-cycle of polymeric material is analysed and discussed.
Course contents
In order to gain the best results from the lessons, students should posses a basic knowledge of organic chemistry and thermodinamics, as well as a general introduction to the different classes of materials. English is the language of the Course
Concept of macromolecule. Synthetic and natural polymers.
Polymers from renewable resources.
Polymerization.
Step-growth and Chain-growth mechanisms. Kinetics. Examples.
Structure of polymeric chains. Conformations and configurations.
General relationships between structure and macroscopic properties.
Molecular weight. Definitions and experimental determination.
Size exclusion chromatography (or GCP).
Crystallization, crystallizzation kinetics and melting process. Amorphous phase and glass transition.
Mechanical properties.
Structure and temperature dependence. Ultimate properties. Elastic modulus. Yielding process. Shear yielding and crazing.
Viscoelastic behaviour Creep and stress relaxation processes.
Dynamic Mechanical Analysis.
Degradation. Causes and effects. Additives preventing degradation
Processing: extrusion and injection moulding
Recycling: problems and opportunities

Teaching methods
Lectures according to timetable
Laboratory lesson: mechanical tests, thermal analysis (DSC and TGA) and Melt Flow Index determination.
Assessment methods
Final written exam (English language).
The exam (lasting about 1 hour) is made of two parts: the first consists of two open questions concerning the topics of the course. The second consists of 10 true/false questions.Examples of previously proposed test are available at "Insegnamenti on line" (IOL)
