Polymer characterization as a source can be divided into 2 categories: polymer synthesis and polymer natural or biological, polymer, polymer-based products include plastic fibers. Rubber, foam, etc.
Polymer by the source is divided into two types of polymer synthesis. And polymer or natural polymer bio. Products from polymer fibers, including plastic, rubber, foam, etc.
Polymer by the source is divided into 2 categories, synthetic polymers and natural polymers or polymer biological products from polymers. Such as plastic, fiber, rubber, foam, etc.
