実験手順
In an atmosphere of dried argon gas, a given amount of tetramethylethylenediamine (TMEDA) was dissolved in a mixed solvent of cyclohexane and n-hexane having a cyclohexane/n-hexane ratio of 9/1 (V/V). The resultant solution was cooled to and maintained at -10° C. Then, in an atmosphere of dried argon gas, an n-hexane solution of n-butyllithium (n-BuLi) was gradually added to the solution of TMEDA in cyclohexane/n-hexane in an amount such as would provide a TMEDA/n-BuLi molar ratio of 1/1. As a result, polymerization catalyst 2 (a complex of TMEDA with n-BuLi) was obtained.
