Career
At Dupont, Collins worked under Wallace Carothers. Carothers assigned Collins to produce a sample of divinylacetylene. In March 1930, while distilling the products of the acetylene reaction, Collins obtained a small quantity of an unknown liquid, which he put aside in stoppered test tubes. He later found that the liquid had congealed into a clear homogeneous mass. When Collins removed the mass from the test tube, it bounced. Further analysis showed that the mass was a polymer of chloroprene, formed with chlorine from the cuprous chloride catalyst. Collins had stumbled upon a new synthetic rubber.
Following this breakthrough, DuPont began to manufacture its first artificial rubber, DuPrene, in September 1931. In 1936, it was renamed neoprene a term to be used generically.
