Why did Thiokol invent sodium polysulfide gum?
In 1926, in the course of an experiment involving ethylene dichloride and sodium polysulfide, they created a gum whose outstanding characteristic was a terrible odor. The substance clogged a sink in the laboratory, and none of the solvents used to remove it were successful.
