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 ...
The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on December 7, 1909. [3] Bakelite was one of the first plastic-like materials to be introduced into the modern world and was popular because it could be moulded and then hardened into any shape.
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.
His work was primarily in the area of plastics and catalysts. In 1951, he invented crystalline polypropylene and high-density polyethylene (HDPE) with his fellow research chemist Robert Banks. The initial research drive was to oligomerize light olefins which were byproducts at the time from catalytic cracking reactions developed during WWII.
John Wesley Hyatt (November 28, 1837 – May 10, 1920) was an American inventor. He is mainly known for simplifying the production of celluloid.. Hyatt, a Perkin Medal recipient, is included in the National Inventors Hall of Fame.

LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. 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]
