Abstract

1442465 Ethylene polymerization in bulk SNAMPROGETTI SpA 24 May 1974 [15 June 1973] 23473/74 Heading C3P Ethylene is polymerized in a reaction medium comprising the liquid monomer in the presence of (a) a transition metal compound and (b) a polyiminoalane i.e. -(-HAl-NR-)- n where R is hydrocarbyl. The polymerization is carried out below the critical temperature of ethylene, and examples refer to the preparation of polyethylenes in liquid ethylene using VOCl 3 or TiCl 4 with a poly(isopropyliminoalane).
