Aims :

The basilar properties of polymers will connected with the various conversion possibilities.
The student will learn main characteristics of vergin plastic materials and of commercial commodities. A particular study will dedicated to rheological behaviour of polymers.

Topics :

Polymeric material:definition. Production of polymeric materials by polymerization: thermoplastic or thermosetting. Polymer structure. Amorphous or semicrystalline structure. Molecular weigth. Phase transformations. Thermal, mechanical and rheological properties. Tests on polymers. Compounds. Viscosity in shear and in elongation. Viscoelastic behaviour. Relaxation time. Principal conversion technologies. Injection molding: design parameters. Molding process cycle.
