Summary
This section covers the essential principles of polymer structure and chemistry. It explains how polymers form from repeated monomer units, describes methods for representing and calculating molecular weights and degree of polymerization, and discusses various structural configurations including linear, branched, crosslinked, and network forms. The section further distinguishes between stereochemical arrangements, thermoplastic versus thermosetting behaviors, and outlines crystallinity and diffusion phenomena in polymers. Understanding these concepts provides a foundation for predicting and tailoring polymer properties for diverse applications.
