In this study, polyisoprene (PI) was synthesized by anionic polymerization using sec-butyllithium and tetrahydrofuran as initiator and solvent, respectively. As a result, PI with a high ratio of 1,2- / 3,4- structures was synthesized. Then dibutylmagnesium and triisobutylaluminum were used as additives to investigate the effect of removing impurities and delaying polymerization. It was observed that the microstructure was not effected by the addition of alkyl metal in anionic polymerization of isoprene. |
