An initiator slurry was prepared by mixing 775.9 ml of 1.3 M sec-butyl lithium in cyclohexane with 4133 g of oxygen-free cyclohexane and stirred at room temperature for about 30 minutes. To this solution was added 196 g of 1,1-diphenylethylene, which resulted in the formation of a red colored solution of 1,1-diphenylhexyl lithium. Purified 2-ethylhexyl methacrylate monomer (pumped via a reciprocating piston pump at a rate of 89.3 g/min) was fed into zone 1 of the 3.3 Liter STR.
