Chapter 4. Styrenic Plastics
4.1. Background
This chapter on styrenic plastics covers a broad class of polymeric materials of which an important part is styrene. Styrene, also known as vinyl benzene, is an organic compound with the chemical formula C6H5CH = CH2. Its structure is shown in Figure 4.1.
