OLEFIN POLYMERIZATION CATALYST AND PROCESS FOR THE PRODUCTION OF OLEFIN POLYMERS

摘要

An olefin polymerization catalyst enabling the production of olefin polymers with excellent polymerization activity and a process for polymerizing an olefin by the use of the catalyst. The catalyst comprises a transition metal amide compound of general formula (I) [wherein M<1> is Ti or the like; R<1> is alkyl, (substituted) phenyl or the like; R<2> is -C(R<5>)2C(R<6>)mC(R<5>)2- or -C(R<5>)2-X<1>-C(R<5>)2- (wherein X<1> is a silicon-containing group or the like; and R<5> and R<6> are each hydrocarbyl or the like); and R<3> is hydrocarbyl, halogeno or the like], and at least one compound selected from among organoaluminumoxy compounds, ionizing ionic compounds and organometallic compounds. The process enables the production of olefin polymers with high polymerization activity to give olefin polymers free from residual odor, and comprises conducting the (co)polymerization of olefins in the presence of a catalyst comprising a transition metal amide compound of the general formula: (R2N)kM<2>X<2>j-k (wherein M<2> is Ti, Zr or the like; j is the valence of M<2>; k is 1 to j; R is hydrogen, hydrocarbyl or the like; and X<2> is halogeno, hydrocarbyl or the like) and an organoaluminumoxy compound, which is added to the polymerization system in a state slurried in an aliphatic or alicyclic hydrocarbon.
