46289 - Chemistry of Synthetic Polymers

Learning outcomes

At the end of the course, the student acquires basic knowledge on macromolecular chemistry as well as on the main characteristics and properties of natural and synthetic polymers used in the field of conservation and restoration of works of art. In particular, the student is able to: a) select the most suitable polymers for each conservation treatment on different historical-artistic artifacts; b) evaluate the performances of protective and consolidant treatments on stone materials; c) evaluate, on the basis of accelerated ageing tests, the endurance of conservation treatments

Course contents

1) Definition and classification of polymers; 2) Main characteristics of  polymers; 3) Natural polymers: source, characteristics and uses; 4) Synthetic polymers: main polymerization processes; 5) Transport properties of small molecules in polymers (outline); 6) Adhesive, cohesive and hydrophobic properties of polymers; 7) Aggregation, consolidation and protection of historical-artistic artifacts with polymers; 8) Evaluation methodologies of aggregating, reinforcing and protective treatments; 8)  The more commonly synthetic polymers used for the restoration of Cultural Heritage: commercial and new products; 9) Advantages and drawbacks of macromolecules for the conservation of Cultural Heritage.

Teaching methods

The subjects will be explained first framing them from a general point of view, then dealing with the problems associated to the application on works of art. During the laboratory experiences, which will flank the theoretic lectures, some tests for the characterization of polymers, as well as examples of treatment and evaluation of the performance of the products used will be carried out.

Assessment methods

At the end of the course, an oral examination will be required. Questions concerning all the topics, treated both during the theoretic lectures and laboratory experiences, will be put.

Teaching tools

Overhead projector, projector, scientific laboratories.
