Course overview and goals
This course that followed "Structure of Organic Materials A" focused on the basics of polymer structure, especially 4. Molecular weight, 5. Polymer crystal, 6. Polymer glass. At first, some examples of manufacturing polymeric materials are explained.
When we use polymers as materials, the control of the physical properties is important. Therefore, it is necessary to know the basic structure of polymers and control the structure for physical properties. It is desirable to understand the basic of the essence of polymers.
Course description and aims
By the end of this course, students will be able to understand:
1)Measurement method of the molecular weight distribution and its principle
2)Basic knowledge about the structure of crystal and amorphous state in polymers
3)Basics of structure formation mechanism in polymeric materials
Student learning outcomes
実務経験と講義内容との関連 (又は実践的教育内容)
When a polymer is used as an actual material, it is important to control its physical properties. For that purpose, it is necessary to know the basic structure and control the structure based on that knowledge. It is very important to understand the content of this lecture as the first entry point (basic) for doing so.
Keywords
Molecular weight distribution, Number-average molecular weight, Weight-average molecular weight, Membrane osmometry, Light scattering method, GPC, Single crystal, Folded chain crystal, Spherulite, Polarized optical microscope, Birefringence, Equilibrium melting point, Depression of melting point, Kinetics of crystal growth, Glass transition
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
Based on power point files, I push forward a lecture with a question. In addition, at the beginning of each class, solutions of quiz (small test) in previous class are reviewed. Towards the end of class, students are given quiz related to the lecture given that day to solve.

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
