Olefin polymer, olefin polymerization catalyst and process for producing olefin polymer

摘要

An olefin polymer selected from the group consisting of a 1-butene homopolymer, a copolymers of 1-butene with propylene and a copolymer of 1-butene with an alkenyl hydrocarbon having 5 or more carbon atoms, wherein said olefin polymer is an amorphous polymer having a polystyrene-reduced number average molecular weight of 200,000 and substantially not having a melting point, an olefin polymerization catalyst obtained by contacting a specific transition metal compound(A), an organoaluminumoxy compound (B) soluble in an aromatic solvent and water (C), and a process for producing said olefin polymer with said catalyst.
