    • In the ethylene polymerizations using the dichloro (1, 2) and the dimethyl (7, 8) analogues in the presence of MAO, a tiny trace amount of high molecular weight polymer was also observed in the GPC trace, although ratios in the dimethyl analogues (7, 8) were extremely low. As commented by reviewers, this may be speculated as due to a probable dissociation of the pyrrolide ligand pyrrolide transfer from Ti to Al, and this may be a reason for the bimodal molecular weight distribution in the resultant polyethylene
