The first industrially practical polyethylene synthesis discovered by Eric Fawcett and Reginald Gibson at the Imperial Chemical Industries (ICI) works in Northwich, England. [10] 1935 Nylon is invented and patented by DuPont [6] 1938: Nylon is first used for bristles in toothbrushes. It features at the 1939 worlds fair and is famously used in ...
Polyethylene was first synthesized by the German chemist Hans von Pechmann, who prepared it by accident in 1898 while investigating diazomethane. [12] [a] [13] [b] When his colleagues Eugen Bamberger and Friedrich Tschirner characterized the white, waxy substance that he had created, they recognized that it contained long −CH 2 − chains and termed it polymethylene.
John Paul Hogan (August 7, 1919 [1] – February 19, 2012) [2] [3] was an American research chemist. Along with Robert Banks, he discovered methods of producing polypropylene and high-density polyethylene.
Plastic consumption differs among countries and communities, with some form of plastic having made its way into most people's lives. North America (i.e. the North American Free Trade Agreement or NAFTA region) accounts for 21% of global plastic consumption, closely followed by China (20%) and Western Europe (18%).
Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1] Its manufacture employs the same method today.

Polythene is the world's most widespread polymer, and was first produced by ICI from 1939; many plastic bottles are made from LDPE. Polystyrene was invented in Germany in 1937. PTFE was discovered in America (New Jersey) in 1938 by Roy J. Plunkett when at DuPont. PET beverage bottles were introduced from 1973. PEEK was developed by ICI in 1977.
