(bio)Polymer Science

Objectives

The objectives of this curricular unit are:

1. To have a knowledge about the mechanisms and kinetics of polymerization reactions, the correlation between the average degree of polymerization and the rate law, the effect of temperature on the rate law and to be able to use them on the design of a polymerization reactor. 

2. To have knowledge about the main industrial polymerization processes, including the synthesis of biopolymers (bioplastics, polysaccharides and protein based polymers).

3. Biopolymers: Classification; Production, extraction methods and purification methods. Design of stimuli-responsive polymeric systems.

4. Depolymerization and upscaling.
