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 a V compound in the presence of monomers and then adding a polysiloxane compound.
CONSTITUTION: In producing 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 prepared by employing a catalyst prepared by contacting an organic Al compound such as ethylaluminum sesquichloride with an organic solvent-soluble V compound such as VOCl3 in the presence of monomers and then adding a polysiloxane compound such as α-methylstyrene-modified polysiloxane.
