Abstract: The discovery of the stereospecific polymerization of isoprene by an anionic mechanism aroused considerable interest both in academic and industrial circles. Polymerization of isoprene by lithium or organolithium derivatives in hydrocarbon solvents is found to propagate via an anionic mechanism and yields a polymer with a high cis-1,4 steric configuration. This synthetic polyisoprene has properties which are similar to those of natural rubber. The anionic polymerization of vinyl monomers initiated by alkali metals, soluble organoalkali metal derivatives, or soluble complexes of alkali metals and polynuclear aromatic compounds shows an absence of any termination step. Each anion continues to add monomer as long as monomer is present, forming the so-called "living" polymers. Thus nearly monodisperse polymers are obtained. The lack of a termination step and the monodispersity of the resulting polymers make possible the study of the absolute kinetics of the initiation and propagation steps in anionic polymerization.
