Polycarbonate is one of those materials that was discovered by accident. A chemist named Einhorn was trying to make cyclic carbonates by reacting phosgene (a very dangerous chemical later used as a chemical warfare agent) with hydroquinone (a phenol used largely as a film developing agent) and got an insoluble solid. Tests at Bayer in the 1950s to find the best phenol led to the discovery the phenol used in epoxy, bisphenol A, was the right phenol to use in polycarbonate.
