- 10.2: Polymers and Plastics
- Synthetic polymers, which includes the large group known as plastics, came into prominence in the early twentieth century. Chemists' ability to engineer them to yield a desired set of properties (strength, stiffness, density, heat resistance, electrical conductivity) has greatly expanded the many roles they play in the modern industrial economy. This Module deals mostly with synthetic polymers, but will include a synopsis of some of the more important natural polymers.
- 10.3: Avoidance of Crystallization in Biological Systems
- This teaching and learning package discusses the two main environmental threats leading to crystallization in plants and animals, and the ways in which organisms have adapted to avoid this crystallization. As part of this discussion, there is coverage of some of the theory of nucleation and crystallization.
- 10.4: Polymer Chemistry
- Polymers are giant molecules (also called macromolecules) that are essential to our existence. They are important chemicals in our bodies (proteins, DNA), in plants (starch, cellulose), and in our everyday lives (fibers, plastics). Polymers are made by transforming small molecules (monomers) into molecules with very large molecular weights. Although the chemical properties of polymers are similar to those of analogous small molecules, their physical properties are quite different.
