Polymeric materials are nowadays employed in a multitude of applications, due to their wide spectrum of chemical, physical and mechanical properties. For this reason, polymeric materials play an important role on the chemical industry and more in general on the global economy. This programme provides a bird’s eye vision about the methods to produce different typologies of polymers and about the processing techniques used to obtain valuable finished products.
Objective
In this programme you will:
- Understand the importance of the polymers economics
- Learn to infer the properties of the polymeric materials from their chemical structure
- Learn the methodologies used to produce polymers from raw materials
- Learn the techniques used to produce reinforced resins
- Listen about the applications of the most common polymeric materials
- Learn the techniques used to form the finished products
- Apply the most important equations governing the chemical and mechanical behaviour of polymers
