Prepolymerized catalyst, catalyst for olefin polymerization, polymerization process of olefin, and olefin polymer

Abstract

The olefin polymer of the invention is an .alpha.-olefin/polyene copolymer-containing olefin polymer comprising (i) an .alpha.-olefin/polyene copolymer and (ii) an olefin polymer, wherein the polyene is an aliphatic polyene having 7 or more carbon atoms and having an olefinic double bond at both terminals, and the .alpha.-olefin/polyene copolymer contains constituent units derived from the .alpha.-olefin in an amount of 99.999 to 70 mol % and contains constituent units derived from the polyene in an amount of 0.001 to 30 mol %, the olefin polymer (ii) is a polymer of olefin having 3 or more carbon atoms, the .alpha.-olefin/polyene copolymer-containing olefin polymer comprises the .alpha.-olefin/polyene copolymer (i) in an amount of 0.001 to 15% by weight and the olefin polymer (ii) in an amount of 99.999 to 85% by weight, and the .alpha.-olefin/polyene copolymer-containing olefin polymer is obtained by using a prepolymerized catalyst containing the .alpha.-olefin/polyene copolymer.
