In this study, polyisoprene was synthesized by anionic polymerization at room temperature using sec-butyllithium as an initiator and tetrahydrofuran as a solvent. As additives, dibutylmagnesium, trioctylaluminum, and triisobutylaluminum, which are alkyl metals, were used. It was observed that the additives did not affect the microstructure of polyisoprene. The effect of delaying polymerization by the additives was observed through the change in yield according to the polymerization time, and it was observed that the additives had an effect of removing impurities when isoprene was polymerized without distillation.
