Nathaniel C. Wyeth (October 24, 1911 – July 4, 1990) was an American mechanical engineer and inventor.He is best known for creating a variant of polyethylene terephthalate that could withstand the pressure of carbonated liquids.
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 ...
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.
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.
They began working together in 1946, and in 1951 invented "crystalline polypropylene" and high-density polyethylene (HDPE). These plastics were initially known by the name Marlex . The polymerization of ethylene was made possible by their discovery of the so-called Phillips catalyst .
Walter Lincoln Hawkins (March 21, 1911 – August 20, 1992) was an American chemist and engineer widely regarded as a pioneer of polymer chemistry.For thirty-four years he worked at Bell Laboratories, where he was instrumental in designing a long-lasting plastic to sheath telephone cables, enabling the introduction of telephone services to thousands of Americans, especially those in rural ...
Alexander Parkes was born at Suffolk Street, Birmingham, the fourth son of James Mears Parkes and his wife Kerenhappuch Childs. Samuel Harrison, described by Sir Josiah Mason as the inventor of the split-ring (or key-ring) and widely credited with the invention of the steel pen, was his great-uncle. [6]
Earl Silas Tupper (July 28, 1907 – October 3, 1983) was an American businessman and inventor, best known as the inventor of Tupperware, an airtight plastic container for storing food, and for founding the related home products company that bears his name, Tupperware Plastics Company.
