<p>The present invention provides a catalyst composition and a method for producing an olefin polymer using the catalyst composition. The catalyst composition is prepared by bringing (A) a transition metal compound, (B) a solid boron compound capable of forming an ion pair with the component (A), (C) an organometallic compound and (D) a compound represented by the following general formula (XIV) and/or the following general formula (XV) into contact with each other in a hydrocarbon solvent, and enables a high catalyst concentration.
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒZ 5 R 14 R 15 €ƒ€ƒ€ƒ€ƒ€ƒ(XIV)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒZ 6 R 14 R 15 R 16 €ƒ€ƒ€ƒ€ƒ€ƒ(XV)
[In the formulae, Z 5 represents an oxygen atom, etc.; Z 6 represents a nitrogen atom, etc.; R 14 to R 16 each independently represent an organic group, and at least one of those organic groups is an organic group having at least 3 carbon atoms, and R 14 to R 16 may bond to each other to form a ring.]</p> |
