Procedure

Similarly as in Example 1, the charge consisted of 48.2 ml of toluene and 0.0343 mol of MMA. The initiator prepared from 0.000286 mol of LiA, 0.00172 mol of sodium tert-butoxide, and 2.8 ml of benzene was added at 20° C. under stirring. After 4 minutes, 0.0343 mol of n-butyl methacrylate was added and the mixture was allowed to react for 1 hour. The block copolymer poly/methyl methacrylate -b- n-butyl methacrylate) was then isolated in the yield of 71%.
