With a variety of polymer materials, a large quantity of production, wide application and great benefits, every walk of life must be involved in the preparation of polymer materials, characterization and determination of their properties and qualities, and their processing and application and so on. So the students out of the major polymer science also need broaden their knowledge information and take in some basic knowledge of polymer science.
