DuPont Central Research was established at the DuPont Experimental Station, across the Brandywine Creek from the original powder mills.

DuPoint Big Automotive investments: 1914


Major breakthroughs: 1920s-1930s

In the 1920s DuPont continued its emphasis on materials science, hiring Wallace Carothers to work on polymers in 1928. Carothers discovered neoprene, the first synthetic rubber; the first polyester superpolymer; and, in 1935, nylon. The discovery of Teflon followed a few years later. DuPont introduced phenothiazine as an insecticide in 1935.
