Polymers

Prior to the early 1920's, chemists doubted the existence of molecules having molecular weights greater than a few thousand. This limiting view was challenged by Hermann Staudinger, a German chemist with experience in studying natural compounds such as rubber and cellulose. In contrast to the prevailing rationalization of these substances as aggregates of small molecules, Staudinger proposed they were made up of macromolecules composed of 10,000 or more atoms. He formulated a polymeric structure for rubber, based on a repeating isoprene unit (referred to as a monomer). For his contributions to chemistry, Staudinger received the 1953 Nobel Prize. The terms polymer and monomerwere derived from the Greek roots poly (many), mono (one) and meros (part).

Recognition that polymeric macromolecules make up many important natural materials was followed by the creation of synthetic analogs having a variety of properties. Indeed, applications of these materials as fibers, flexible films, adhesives, resistant paints and tough but light solids have transformed modern society. Some important examples of these substances are discussed in the following sections.

Why study chemistry?

We all do chemistry every day! As soon as you wake up in the morning, you start doing chemistry. Chemistry explains why an egg changes when you fry it and why your non-stick pan is non-sticky. Chemistry explains how soap and shampoo make you clean, why you feel tired before coffee and alert after it, and how the petrol in your car gets you to work. One of our first year labs helps you understand why perfumes smell the way they do. In fact you start doing some chemistry yourself as soon as your eyes open - your sense of vision works because a small organic molecule changes shape in the back of your eye when light hits it.
