    • PURPOSE: An olefin polymerization catalyst is provided to obtain various catalysts through compound combination and easily regulate composition distribution of olefin polymer or copolymer, and molecular weight. CONSTITUTION: An olefin polymerization catalyst contains; an organic compound of chemical formula 1(R^1_l-H or R^1_l-Q-R^1_l), an organic metal compound of chemical formula 2(^1R^2_mR^3_nR^4_pR^6_q), an organic transition metal compound of chemical formula 3(M^2R^7_rX_s), and aluminoxane. The olefin polymerization catalyst is immersed in an organic or inorganic carrier. A method for preparing the olefin polymerization catalyst comprises: a step of contacting the olefin polymerization catalyst with a porous carrier to obtain slurry mixture; a step of reacting the slurry mixture at 0-120°C for one to six hours to uniformly penetrate the catalyst components; and a step of drying the catalyst components through vacuum or nitrogen flow to obtain the solid catalyst.
