Abstract
1466848 Ethylene polymerization in bulk SNAMPROGETTI SpA 24 May 1974 [15 June 1973] 08378/76 Divided out of 1442465 Heading C3P Ethylene is polymerized in a reaction medium comprising the liquid monomer in the presence of a catalyst comprising (A) an organoaluminium compound of formula RAlX 2 where R is hydrocarbyl and X is halogen and (B) a vanadium compound of the formula V(NR<SP>1</SP>) 4 where R<SP>1</SP> is hydrocarbyl. The process is carried out below the critical temperature of ethylene and at a pressure at or slightly above the vapour pressure of liquid ethylene at the polymerization temperature. The example refers to the preparation of polyethylene in liquid ethylene using EtAlCl 2 and V(NMe 2 ) 4 .
