Procedure

To a 500 ml Schlenk tube, in which a magnetic stirrer chip was put, was added 2.0 g of 1,1-diphenylethylene and then the inside thereof was replaced by nitrogen. Thereto were added 190 ml of toluene and 7.7 ml of a cyclohexane solution of sec-butyllithium (concentration: 1.3 M). The resultant solution was stirred at room temperature for 2 days to conduct reaction. In this way, a toluene solution of 1,1-diphenyl-3-methylpentyllithium (DPMPLi) (concentration: 0.05 M) was obtained. Example 11 (Polymerization example of methyl methaciylate, using 1,1-diphenyl-3-methylpentyllithium)
