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.
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 .
