Title: CATALYST COMPOSITION AND PROCESS FOR PRODUCTION OF OLEFIN POLYMERS USING THE CATALYST COMPOSITION
Abstract:
Disclosed is a catalyst composition which is obtained by bringing (A) a transition metal compound, (B) a solid boron compound that, together with the component (A), can form an ion pair, (C) an organometallic compound, and (D) a compound represented by general formula (XIV): Z5R14R15 and/or general formula (XV): Z6R14R15R16 into contact with each other in a hydrocarbon solvent, and which enables a high catalyst concentration. Also disclosed is a process for the production of olefin polymers using the catalyst composition. In general formulae (XIV) and (XV), Z5 is an oxygen atom or the like; Z6 is a nitrogen atom or the like; and R14 to R16 are each independently an organic group, at least one of R14 to R16 being an organic group having three or more carbon atoms, or R14 to R16 may unite with each other to form a ring.
