Scripts - Physical Chemistry of Polymers 1 (login with your JGU account)



This lecture aims at establishing a basis of knowledge and competence for understanding fundamental structure–property relations of polymers, such to arc further teaching contents in the fields of polymer chemistry and materials engineering.



Basic knowledge in organic and physical chemistry as well as mathematics, as taught in bachelor-level classes of these fields.



09.032.641 Lecture: Introduction to Macromolecular Chemistry: Physical Chemistry of Polymers


Preface to the Winter Term 2020/21


Dear students:

Still, the pandemic of the SARS-CoV2 pathogen does not allow classical lecture courses to be held in this semester.  To keep protective distance, the lecture is therefore moved from the lecture hall to your own apartment.  For this purpose, short scripts, each covering one of a total of nine lesson units of this lecture, are available to you as working materials in the "Scripts" section of this website and (alternatively), on our university`s e-learning platform Moodle.  In addition, nine accompanying digital lectures, in the format of both a video and an audio-podcast each, are available to you for streaming on this website and on Moodle.  You can view/listen them at home, supported by the scripts, and thus consume the lecture contents conveniently from your private place.  As further accompanying material, the textbook "Physical Chemistry of Polymers" (S. Seiffert, DeGruyter 2020) is recommended, which presents the content in even greater depth and detail.

Accompanying to the lecture, there is an exercise in digital format.  You can download exercise sheets in the "Scripts" section of this website or also in Moodle and solve them at home.  Please make your solutions by hand, scan them or take a photo of them, and send this to Ms. M.Sc. Martha Koziol (mkozio01[a]  You will then receive personal feedback from her.  Participation in this exercise is voluntary and has no consequences for the completion of the module; however, active participation is strongly recommended, as it turned out in the past that this leads to significantly more efficient learning for the exam in the end…and that the exam is then typically also passed with significantly better results.

Your teachers,
Prof. Dr. Sebastian Seiffert
M.Sc. Martha Koziol
