Students will prepare a synthetic elastomer called Thiokol$^®$. This polysulfide was the first synthetic rubber produced by Dr. Joseph C. Patrick in the 1920s. Students will synthesize this material by combining an alkylene dichloride and sodium polysulfide. This is an interfacial polymer reaction but unlike the nylon $ \large\frac{6}{10}$ the polymer forms at the bottom of the beaker.
