Chemical production
In the late 1950s and early 60s, Amoco again led the way with scientific and technological discoveries. Amoco discovered PTA, a chemical for polyester fiber production. In 1968, following that discovery, Amoco acquired the Avisun Corporation and Patchogue-Plymouth, forming the Amoco Fabrics and Fibers Company.
