1.2.4 Conveying information to others

Diagrams are used extensively in most types of texts, but why do authors use them? There are two main reasons:

  • to illustrate what something looks like;

  • to demonstrate how objects or ideas or quantities are organised or related.

4.6 Polymer grades

Polymers synthesised by a variety of routes are available in many grades from the large polymer manufacturing companies. Naturally enough, the grades of bulk tonnage polymers, such as LDPE, PVC, HDPE and PP, run into the hundreds simply because of the multiplicity of different process routes and end functions. So what are the basic differences between grades of just one polymeric material? The most important distinguishing characteristics are structure and molecular mass.
