A kinetic study was made of the polymerization of butadiene and styrene in an aliphatic hydrocarbon solvent with the use of butyllithium as an initiator. It is shown that the anomalous behavior in the initiation reaction exhibited by isoprene under these conditions is also found for these two monomers. These monomers give a sigmoidal rate curve in the initiation reaction in cyclohexane solution, and the reaction appears to be auto-catalytic. The propagation reactions were studied also, and the results compared with the rather discordant sets of data published by other authors. Author
