OLEFIN POLYMERIZATION CATALYST AND POLYMERIZATION PROCESS

摘要

An olefin polymerization catalyst having an excellent polymerization activity and an olefin polymerization process using the catalyst are disclosed. The olefin polymerization catalyst comprises (A) a transition metal compound represented by, for example, the following formula (I) and optionally (B) at least one compound selected from an organometallic compound, an organoaluminum oxy-compound and a compound which reacts with the transition metal compound (A) to from an ion pair; wherein M is a transition metal atom of Group 3 to Group 11 of the periodic table; m is an integer of 1 to 6; A is -O-, -S-, -Se- or -N(R5)-; D is -C(R<7>)(R<8>)-, -Si(R<9>)(R<10>)- or the like; Z is -R<13> and -R<14>, =C(R<15>)R<16>, =NR<17> or the like; R<1> to R<17> are each H, a hydrocarbon group or the like; n is a number satisfying a valence of M; and X is halogen, a hydrocarbon group or the like.
