16. Degassed MMA (10 mL) was added to CuBr (0.134 g) in a Schlenk tube previously purged with nitrogen. N-n-pentyl-2-pyridylmethanimine (0.33 g) and degassed xylene (20 mL) were added and the solution heated to 90°C prior to addition of 2-bromo-2-methylpropionic acid, 1 (0.156 g). [MMA]:[CuBr]:[N-n-pentyl-2-pyridylmethanimine]:[1] = 100: 1:2:1. Conversion was measured by gravimetry.
17. Polymerizations carried out as in ref 16 except for 10 mL of xylene (50 wt %), N-n-butyl-2-pyridylmethanimine used as Schiff base ligand, and ethyl-2-bromoisobutyrate, 2, used as initiator. [MMA]:[CuBr]:[N-n-pentyl-2-butylmethanimine]: [2] = 100:1:3:1.
