Charles Nelson Goodyear (1800–1860) was an American chemist, inventor, and industrialist. He is credited with discovering [[Vulcanization|vulcanization]] for [[Cross-linking Elastomers|cross-linking]] rubber. In vulcanization, raw rubber is kneaded with 3 to 5 % sulfur and then heated to temperatures of approximately 140 °C. The term vulcanization is derived from volcanoes, where sulfur and heat play a dominant role.

The invention of vulcanization was not the result of systematic research involving a series of experiments, but rather a sheer coincidence. According to tradition, a sulfur–rubber mixture fell onto a hot stove top, and the result was a dry and permanently elastic substance. When heated, the rubber mixed with sulfur transformed into a new material, rubber.

The properties can be specifically adjusted by varying the amount of sulfur used (see: rubber elasticity). In 1850, the production of hard rubber began, which can contain up to 20% sulfur.

It was not until years later that the chemist Hermann Staudinger (1881–1965), who is considered the founder of macromolecular chemistry, succeeded in scientifically understanding the problem. Staudinger coined the term “macromolecule” in 1922. He was awarded the Nobel Prize in Chemistry in 1953 for his research in the field of [[Material Science & Plastics|polymer science]].
