Abstract
Nickel precursor [bis(N,N'-dimesitylimino)acenaphthene]dibromonickel ((MesB IAN)NiBr2, 1) and MAO were used to catalyse the copolymerisation of acrylam ide (AA) and ethylene (E) by passivating AA with triisobutylaluminium (TIBA ), trimethylaluminium (TMA) or Et2AlCl (DEAC). The activity with TIBA is as high as 1.04x10(6) g/(mol Ni . [E] . h). Acrylamide-ethylene copolymerisat ion activity of 2.5 x 10(5) g/(mol Ni . [E] . h) was achieved using MgBu2/E t2AlCl as cocatalyst for 1 in the absence of MAO. Acrylamide was also terpo lymerised with ethylene and propylene.
