Abstract:
A process for producing an olefin polymer which comprises polymerizing an .alpha.-olefin or copolymerizing two kinds or more of .alpha.-olefins with an olefin polymerization catalyst using an olefin polymerization catalyst component represented by the general formula (1): ##STR16## wherein M is the transition metal element of the 4.sup.th Group or the Lanthanide Series in the Periodic Table; each of A and A' is the same or different and is a hydrocarbon or halogenated hydrocarbon having 1 to 50 carbon atoms, or a hydrocarbon or halogenated hydrocarbon group having 1 to 50 carbon atoms and a substituent containing an oxygen atom; E is a residual group of an element of the 13.sup.th, 14.sup.th or 15.sup.th groups capable of forming bonds at three positions; each of R and R' is the same or different and is a halogen atom or a hydrocarbon group having 1 to 20 carbon atoms; R"" represents a hydrocarbon or halogenated hydrocarbon group containing at least one hetero atom and having 1 to 20 carbon atoms; anda composition (A) described below:(A) any of compounds (A1) to (A3) below or an admixture of two or three compounds thereof; wherein(A1) is an organoaluminum compound indicated by the general formula R.sup.1.sub.a AlX.sub.3-a,(A2) is a cyclic aluminoxane having a structure indicated by the general formula {--Al(R.sup.2)--O--}.sub.b, and(A3) is a linear aluminoxane having a structure indicated by the general formula R.sup.3 (R.sup.3 --Al--O).sub.c AlR.sup.3.sub.2, wherein each of R.sup.1, R.sup.2 and R.sup.3 is the same or different and is a hydrocarbon group having 1 to 8 carbon atoms; X represents a hydrogen atom or a halogen atom and may represent two or more different atoms; a is a number satisfying 0<a.ltoreq.3, b represents an integer of 2 or more and c represents an integer of 1 or more.
