COURSE DESCRIPTION

Course objectives

- Understanding the modern processing of polymers
- Understanding the modern methods of polymer waste recovery
- Implementation of the adopted knowledge in finding optimal solutions in the processing and recovery of polymers

Course enrolment requirements and entry competences required for the course

 

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, the student is expected to be able to:
- identify and compare the properties and behavior of the polymer in processing and application
- explain the importance of polymer additives
- separate and identify additives polymers
- describe and select proper procedure for polymer processing
- argue selection of the optimal recovery of waste
- argue the importance of polymers in modern society

Course content broken down in detail by weekly class schedule (syllabus)

1st week: Historical development of processes for production of polymer products. Croatian plastics industry. Basic concepts, nomenclature of polymers.
2nd week: Types of polymers: thermoplastics, thermosets, elastomers, thermoplastic elastomers. Systematization of polymer processing. Phase and the physical states of the polymers.
3rd week: Mechanical and thermal properties of polymers.
4th week: Rheological properties of polymers.
5th week: Additives to polymers. Mixing.
6th week: Continuous primary shaping processes: calendering, continuous coating.
7th week: Extrusion

Grading and evaluating student work in class and at the final exam

Continuous evaluation:
The entire exam can be passed over two colloquium during the semester. Pass threshold for each colloquium is 50%. Each colloquium participates with 35% in a final grade. Laboratory exercises (50-100% success) participate with 20% in a final grade, while attending lectures in 80-100% amount is 10% of a final grade.
Final evaluation:
One passed colloquium (previous activity) is recognized as 10% of a final grade. The remaining part is taken on written and oral exam at prescribed examination terms. Written exam accounts for 30%, oral exam for 40%, while laboratory exercises account for 20% of a final grade, respectively.
Students who did not take or pass colloquiums take written and oral exam at prescribed examination terms. Passing threshold is 50%. Written exam accounts for 40%, oral exam for 40%, while laboratory exercises account for 20% of a final grade, respectively.
Grades definitions and percentages: sufficient (50-61%), good (62-74%), very good (75-87%), excellent (88-100%).

Quality assurance methods that ensure the acquisition of exit competences

Quality assurance will be performed at three levels:
(1) University Level;
(2) Faculty Level by Quality Control Committee;
(3) Lecturer’s Level.
