Carothers esters
DuPont’s early polyesters were a sideshow to nylon.
Polyester did not arrive as a finished commodity. Whinfield & Dickson 1941 / DuPont Dacron around United Kingdom / US still explains who makes it and which tests it sits in.
Ten dated points, five eras and three milestones below are the spine — not a complete industrial history.
