Print It has been 90 years since the first ready-to-use polystyrene was invented. Throughout its existence, polystyrene has enabled innovations in industries including health care, construction, food packaging and more. But what developments still lie ahead in the next 90 years for this indispensable material? A German pharmacist, Eduard Simon, first unknowingly discovered polystyrene as early as 1839 by isolating a substance from the bark of a styrax tree that he called styrene (German: Styrol). The road to the production of polystyrene was paved in the years 1929 and 1930 through patents and perfecting recipes. In 1931, earlier challenges were overcome by introducing the first ready-to-use polystyrene or Polystyrene II, as it was initially called produced by degassing volatile components in a vacuum. Later enhancements of the production process resulted in improved material at a higher degree of polymerization: Polystyrene III and Polystyrene IV.
