“Mesoamericans Were The First Polymer Scientists
Ancient Mesoamerican peoples manufactured rubber from latex some 3,500 years before the modern invention of vulcanization and even compounded it for different applications, says new research from a Massachusetts Institute of Technology research team.
According to archaeology professor Dorothy Hosler and technical instructor Michael Tarkanian of MIT’s Department of Materials Science and Engineering, pre-Hispanic peoples not only invented rubber, but they perfected a system of chemical processing to enhance rubber’s properties.
