摘要
研究了以四甲基乙二胺 (TMEDA)为调节剂体系的异戊二烯阴离子均聚合动力学。获得了不同n(TMEDA)∶n(Li)及聚合温度对动力学的影响情况。从理论上对聚合机理进行了推导和论证 。
Using N,N,N',N' tetramethylethylenediamine(TMEDA) as polar additive,the kinetics of anionic polymerization of isoprene initiated with n BuLi in cyclohexane was studied.The effects of TMEDA/Li(mole ratio) and reaction temperature on the polymerization rate were observed.The polymerization mechanism was investigated in theory and confirmed by experiments.The polymerization active energies in different conditions were obtained by Arrhenius equation.
