Chemical Engineering

Overview on polymer, story, diffusion, chemical structure, the concept of macromolecola. Basical: average molecolar weight (difference between numerical and ponderal one) Different way of polimerizzation (Additional way condensation way). Concept of "tacticity". Thermoplastic, Thermosetting, and elastomeric class of material. Eterofasic blends. Different classis of polymers. Science of material: the amorphous phase, the glass transition; cristallinity of polymers, differential scanning calorimetry (DSC). Elastic microstrucrure of elastomeric material. Element of viscoelasticity (model of Maxwell -Voight) and mechanical properties of polimeric materials. Mechanical properties versus temperature and speed of loading. Creep, stress relaxation. Multicomponent polimeric sistems: Reinforced plastics foamed plastics General on composites material, micromechanics and macromechanics of laminates composites material. Basics on "biosusteining" and "biodegradable" composites material Process and technology of transformation: Injection, Extrusion, Blowing, rotational moulding, Special process for termosetting materials fiber reinforced. Elements of design with sandwich structure. Elements of design with foamed polymer.

It is very helpful for the student taking this course to have a good knowledge gained from the materials science course so as to understand both the microstructure-property relationships arising from both the physical and chemical behavior of polymeric materials and/or especially the various and very different mechanical and chemical/physical behaviors of polymeric materials.
