General Information
Groups (& dates) for the lab experiments will be assigned during the safety briefing on Wednesday, 10th of April 2019 at 2 pm (foyer TC-building).
Here you will find general information about the lab course in polymer science.
The lab course includes four experiments:
VIS...Viscometry
CAL...Investigation of emulsion polymerization in a calorimeter
RTD...Residence time distribution in a tubular- and tank reactor
DSC...Investigation of initiator decomposition via Differential Scanning Calorimetry
Dates and Supervisors for the Experiments

Reports
A report should be divided into:
- Introduction
- Theoretical background
- Experimental setup and procedure
- Results and Discussion
- Summary
- References
Further Information & Oral Exam
After all experiments have been done, an oral exam about the lab course takes place. The grade is influenced by this exam, the lab work and the reports.
o Things to be done before experiment starts:
- Reading and understanding the experimental manual
- Knowing the experimental setup and the experimental steps
- Think about questions concerning the experiment
- A talk with the assistant about the experiment and the theoretical background (15-30 min.)
o Observations should be noted, at least one USB stick per group should be exist to save experimental data of DSC, RTD and CAL
o Each group have to write one report for each experiment and have to send it by email or bring it to the assistant within one week! If a correction is necessary, it has to be done within another week. Each report will be graded and influences your experimental grade.
o A report contains of an introduction, a theoretical background, a description of experimental setup and procedure, results, a discussion and a summary.
o Copying from others, taking parts one by one of literary sources, absence in lab leads to failing the course!
o After all experiments have been done, an oral exam about the lab course takes place. The grade is influenced by this exam, the lab work and the reports!
You have an oral exam about the practical course. It is a group examination. The oral exam takes place at the TC building in the social room TC 116.
