This course gives an overview of synthetic polymer chemistry and polymerization mechanism. Driving forces for the initiation of various polymerization methods, such as addition polymerization, polycondensation, ring-opening polymerization, and metal-catalyzed polymerization,are explained. In particular, the kinetics and theory of radical polymerization and polycondensation are explained in detail, and the key factor in determining molecular weights and polydispersity is shown. Also, the historical discovery of controlled polymerization methods, such as anionic polymerization and metal-catalyzed polymerization, is introduced. In addition, the synthesis and properties of branched polymers and networked polymers are shown.
By the end of this course, students will:
1) Gain the fundamental knowledge about the synthetic polymer chemistry.
2) Understand the factors in determining molecular weights and polydispersity in both cases of chain-growth polymerization and step-growth polymerization.
3) Develop practical skills for designing commodity plastics.
Polymers, organic chemistry, radical polymerization, kinetics, molecular weight distribution, copolymerization, ionic polymerization, living polymerization, metal-catalyzed polymerization, stereochemistry, ring-opening polymerization, polycondensation, polyaddition, nonlinear polymers, polymer reactions
|Intercultural skills||Communication skills||Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
In the first half of the class, a summary of the previous lecture followed by the main points of the day's lecture are given. In the latter half, these main points are discussed in detail. Students are asked to provide solutions to some of the questions that have been posed as necessary. Always check the required learning for each class and be sure to complete them as part of preparation and review.
