The teaching “Synthesis and Industrial Production of Polymers” provides the general concepts of polymers synthesis, necessary to address their production on a large scale.
AIMS AND CONTENT
The purpose of the teaching is to learn the methods of synthesis of polymeric materials. In particular, the theoretical bases provided as well as the previous knowledge of kinetics, thermodynamics, reactoristics and those of organic chemistry, will allow to face the problems related to the industrial production of mass-consumption polymers.
AIMS AND LEARNING OUTCOMES
The aim of the teaching “Synthesis and Industrial Production of Polymers” is to provide the general concepts of polymers synthesis, necessary to address their production on a large scale. At the end of the course, by attending and participating the proposed educational activities and by the individual study, the students will be able to: i) know the methodologies for the synthesis of industrial interest macromolecules, ii) deduce, on the basis of the chemical-physical properties of the used monomers, the most suitable synthesis method and iii) establish the polymerization conditions (temperature, time, type of reactor, etc.) on the basis of the final characteristics of the polymer material and the cost-effectiveness of the process. For students following 4 credits, the number of examples related to the industrial production of polymers will be reduced.
The course includes also lectures carried out through discussion with the students. Copies of the slides, presented during the lessons, will be available on AulaWeb and can be used as a basis for the study. Indeed, the exam preparation should to be accomplished by the lessons attendance as well as by the study of the suggested texts. In order to stimulate the discussion with students, scenarios will be proposed which could present only relevant information (defined as well structured) or even irrelevant information (defined as ill-structured). This didactic method will be applied to describe a real or hypothetical situation, short and general, which will allow discussing and taking decisions.

TEACHERS AND EXAM BOARD
ORIETTA MONTICELLI (President)
The start of the lessons will be available on the Degree Course website (https://chimica.unige.it/node/389).
L'orario di tutti gli insegnamenti è consultabile all'indirizzo EasyAcademy.
Oral exams. In case of emergency and only according to specific indications by the University of Genoa, the assessment method for the exam might be changed, including the possibility of an online procedure. In general, two questions will be asked, each weighing 50% on the final evaluation, one on the theoretical aspects of polymer synthesis and one on industrial polymerization examples.
For students with disabilities or with SLD, the examination methods are in accordance with the University Regulations for carrying out the exams (https://unige.it/disabilita-dsa).
The student's reasoning ability as well as his capacity to solve small practical problems will be evaluated. The exam will assess the acquisition of the main concepts concerning the preparation of polymer materials and the student’s capacity to apply them to simple real situations. The Commission is made up of at least two components, one of which is the person responsible for the teaching. With these modalities, the Commission will be able to verify the achievement of the educational objectives of the teaching. In the case these are not achieved, the student will be invited to deepen the study also requesting any additional explanations to the teacher.
