Contribution of the course to the overall degree programme goals
The course specific task is to introduce the student to the interdisciplinary world of polymer chemistry and physics. As matter of fact, today, polymers find widespread application either as materials for artistic expression either as materials for conservation of objects of cultural, historic and artistic interest.
Expected learning outcomes
a) Basic concepts: monomer, repeating unit, macromolecule. Polymer architectures isomeries.
b) Polymer physics. Amorphous and cristalline polymers. Tm and Tg.
c) Adhesion.
d) Materials for consolidation.
e) Coatings and film formation.
f) Polymers as artistic materials.
2. Skill in applying knowledge and understanding
a. Conditions for solubility of a polymer.
b. Techniques for the determination of the PM of the polymer.
c. Understanding of the causes of polymers degradation.
d. How to choose a suitable polymer for a specific application?
3. Judgement skills
a. Choice of the polymeric material most suitable for a remediation in relation with reversibility and time.
4. Comunication skills
a. Acquaintance with the polymer chemistry terminology.
b. Ability in suitably discuss the issues connected with the use of polymeric materials in conservation.

Assessment methods
The verification of the learning is carried out through an oral test which consists of two parts:
1) the presentation of an in-depth analysis of a topic of the Course performed by slides (maximum15 minutes), with the aim of verifying the student's ability to independently process the information received; 2) a series of open questions relating to the topics of the lectures (theoretical part). The student will have to present in formally and scientifically correct language, demonstrating at the same time to have understood the link between the theoretical aspects and their correlation with the laboratory experiences. In particular, the oral test is aimed at ascertaining familiarity with:
- the language of macromolecular chemistry
- the use of polymeric materials in conservation.
The oral test lasts from 30 to 45 minutes based on the clarity of the answers.
The final mark of the course is determined by:
- topic and insights of the presentation (max 8 points)
- exposition of the presentation and graphic appearance (max 4 points)
- knowledge of the required topics (range 10 points);
- exposure (max 2 points);
- ability to independently articulate the speech (max 3 points);
-active participation in laboratory activities (max 3 points).
