Abstract

PURPOSE: To produce titled rubber having an increased tensile strength, a decreased strain and a narrow MW distribution, by employing a catalyst prepared by contacting an organic Al compound with an organic solvent-soluble V compound at a specific low temperature in the presence of monomers.
CONSTITUTION: In the production of a rubbery copolymer by copolymerizing ethylene with an α-olefin such as propylene and, if necessary, at least one nonconjugated diene such as ethylidenenorbornene; the olefin copolymer rubber having a narrow MW distribution is produced by employing a catalyst prepared by contacting an organic Al compound such as ethylaluminum sequichloride with an organic solvent-soluble V compound such as VOCl3 at a low temperature (below 5°C) in the presence of monomers.
