Aim
The aim of the course is to acquaint students with the structure of polymers as structural materials, the dependence of their properties on the structural structure, temperature, environmental influences, and the peculiarities of their stress-strain relationships. Basic polymer processing technologies such as compounding, extrusion, coextrusion, calendering, injection molding, rotational molding, and composite manufacturing technologies are discussed. In addition, we discuss the application technology of polymers and the possibilities of recycling.

In some situations, as part of a team, you work with your fellow students to solve tasks. With his knowledge, he makes a responsible, well-founded decision based on his analyzes. It is responsible for the accuracy and usability of the material properties it provides. He is committed to the precise execution of measurement and laboratory work. Collaborates with the instructor and fellow students to expand knowledge.
Teaching methodology
The teaching of the subject takes place in the framework of lectures and laboratory practice. The lectures basically introduce students to the information defined by the knowledge competence elements using the technique of frontal education. The application and skill-level acquisition of knowledge takes place in laboratory exercises, different tasks have to be solved in groups. Laboratory sessions promote the application of knowledge and the acquisition of skills at a practical level by presenting what has been said in lectures in practice and performing measurement tasks. Students acquire the competency elements of ability, attitude, and autonomy and responsibility essentially by completing laboratory exercises.

General rules
In the diligence period: The condition for obtaining a signature at the end of the semester is the successful completion of 10 laboratory practices without exception. At the beginning of the laboratory internships, students write a pop-up ZH, which is considered successful if the student writes it to more than 40%. The student can then take part in the lab exercise. Depending on the result of the incoming ZH, the student may collect points as follows: 41% -70%: 0 points; 71% -85%: 1 point; 86% -100%: 2 points. The subject ends with an oral exam, the success of which is conditional on passing more than 40%. The exam itself is 80 points, so the exam mark is determined on the basis of the following point limits: In case of credit points: 0-40: insufficient; 41-55: sufficient; 56-70: medium; 71-85: good; 86-100: jeles. Based on exam performance only: 0-32: insufficient; 33-44: sufficient; 45-56: medium; 57-68: good; 69-80: excellent. The student receives the grade based on the more favorable scoring system.
Assessment methods
Detailed description of mid-term assessments
| Mid-term assessment No. 1 | ||
| Type: | diagnostic assessment | |
| Number: | 10 | |
| Purpose, description: | The condition for obtaining a signature at the end of the semester is the successful completion of 10 laboratory practices without exception. A student who does not show up by the start date of the lab will not be able to attend the lab. Only students who have brought the obligatory equipment with them can take part in the laboratory exercises: their own, blank protocol, calculator, identity card. During laboratory internships, students appear prepared based on pre-issued aids. At the beginning, students write a pop-up ZH (level assessment), which is considered successful if the student writes it to more than 40%. The student can then take part in the lab exercise. | |
Detailed description of assessments performed during the examination period
Elements of the exam:
| Oral partial exam | ||
| Obligation: | mandatory (partial) exam unit, failing the unit results in fail (1) exam result | |
| Description: | In the oral exam, we ask for the material of the whole semester to be counted, ie in addition to the materials of the lectures, we also check the competence elements to be acquired in the laboratory practice. At the beginning of the exam, the student is given 3 questions related to different subject areas, which he or she has an adequate amount of preparation time to answer. The exam can be successful if the student gives meaningful answers to all the questions. Successful completion of the exam requires a performance of more than 40% on the exam. | |
| Inclusion of mid-term results | ||
| Obligation: | optional (partial) exam unit, which can be taken into account only if it is favourable for the student | |
| Description: | Laboratory points earned during the semester may count towards the exam. In laboratory exercises, depending on the result of the incoming ZH, the student may collect points as follows: 41% -70%: 0 points; 71% -85%: 1 point; 86% -100%: 2 points. The exam itself is 80 points, so the exam mark is determined on the basis of the following point limits: In case of credit points: 0-40: insufficient; 41-55: sufficient; 56-70: medium; 71-85: good; 86-100: jeles. Based on exam performance only: 0-32: insufficient; 33-44: sufficient; 45-56: medium; 57-68: good; 69-80: excellent. The student receives the grade based on the more favorable scoring system. | |

| new result overrides previous result | ||
| Completion of unfinished laboratory exercises: | ||
| missed laboratory practices must be performed in the teaching term at pre-arranged appointment | ||
