Joseph C. Patrick
Dr. Joseph Cecil Patrick (1892–1965) invented America's first synthetic rubber in the early 1920s.〔(【引用サイトリンク】url=http://pslc.ws/macrog/exp/rubber/synth/thiokol.htm )〕 While seeking a formulation for automotive antifreeze, he attempted to hydrolyze ethylene dichloride with sodium polysulfide. In doing so, he produced a brown, insoluble gum that later became known as Thiokol. He solved commercial production problems by inventing the suspension polymerization process, and solved compounding problems by degrading high molecular weight polymer to a low molecular weight liquid polymer. This material is one of the principal binders for rocket propellant.
Patrick was the 1958 recipient of the Charles Goodyear Medal.
