Abstract:
A polymerization to form a branched polyolefin, in which polymerization an ethylene copolymerization catalyst and an ethylene oligomerization catalyst form a series of ethylene oligomers that are α-olefins are both present, gives an improved polyethylene if the oligomerization catalyst has a relatively high Schulz-Flory constant.
