Course description and aims

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.

Student learning outcomes

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


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 that will be developed

Intercultural skills Communication skills Specialist 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.
