In 1926, chemist Waldo Semon at B.F. Goodrich accidentally discovered a way to make polyvinyl chloride (PVC) commercially viable while attempting to create a rubber adhesive. His work transformed PVC from a laboratory curiosity into a widely used plastic found in various products today.
- 01Waldo Semon's initial goal was to create an adhesive to bond rubber to metal, but he instead discovered a flexible form of PVC.
- 02PVC was first synthesized in the 19th century but was not commercially viable due to its rigidity until Semon's modifications.
- 03The introduction of plasticisers allowed PVC to be processed without degradation, leading to its widespread industrial use.
- 04By the mid-20th century, PVC became essential in various applications, including rainwear and plumbing.
- 05Semon's discovery exemplifies how unintended outcomes in scientific research can lead to significant innovations.

In 1926, chemist Waldo Semon at B.F. Goodrich aimed to develop a better adhesive for rubber and metal but stumbled upon a flexible form of polyvinyl chloride (PVC) instead. Initially, PVC had little commercial value due to its rigidity, despite being synthesized as early as 1835. Semon's experiments revealed that heating PVC in a solvent created a jelly-like substance that became flexible upon cooling. This led to the development of plasticised PVC, which could be processed without degradation. The addition of plasticisers made it possible to manufacture PVC in large volumes, opening the door for its use in various products, from raincoats to plumbing pipes. By the mid-20th century, PVC emerged as one of the most widely produced plastics globally, showcasing the importance of recognizing potential in overlooked materials. Semon's accidental discovery serves as a reminder of how scientific innovation can stem from unexpected outcomes.
