Procedure

An initiator slurry was prepared by mixing 712 ml of 1.3 M sec-butyl lithium in cyclohexane with 2949 g of oxygen-free toluene and stirred at room temperature for about 10 minutes. To this solution was added 167 g of 1,1-diphenylethylene, which resulted in the formation of a red colored solution of 1,1-diphenyhexyl lithium. Purified isodecyl methacrylate monomer (pumped via a reciprocating piston pump at a rate of 11.5 g/min), and purified toluene solvent (pumped via an reciprocating piston pump at a rate of 27.8 g/min) were fed into zone 1 of the 2L stainless steel STR through a heat exchanger immersed in a −78° C. bath. The batch temperature profile of the STR zones prior to catalyst addition was as follows: #1=−64° C., #2=−63° C., #3=−63° C., #4=−54° C.
