KEVLAR® is a compound that was invented in the early 1960's by Stephanie Kwolek.  The compound that she  created was predicted to be five times stronger than steel and weighed far less. She patented the compound in 1966. She worked in Dupont's research lab as soon as it opened in 1950. Kwolek's job was to find new and stronger polymers. She created polymers by synthesis and one day created a polymer in a test tube  that was a cloudy solution, but Dupont wasn't interested in a non-clear polymer solution. Kwolek insisted on spinning, which would cause the Kevlar in the solution to become separated from the solution. Her insistency returned an incredibly useful compound. This compound would soon find many uses and would save thousands of lives.  KEVLAR® is created through a process called interfacial polymerization which uses the process of synthesis at very low temperatures.
