Teaching Pattern

Methodology Basic principles will be introduced and discussed in lectures, and further consolidated through class exercise and tutorials. Fundamental knowledge gained will be applied through independent learning of a variety of commercial products. Student’s competence in Polymer Chemistry will be developed through class presentation of selected commercial products and receiving feedback from fellow students.
