Catalyst for polymerization of propylene and method for polymerization of propylene using the same

1. A method for preparing a catalyst for propylene polymerization, wherein the method comprises:

obtaining a dialkoxy magnesium carrier by reacting metal magnesium with 5-50 parts by weight of an alcohol, based on 1 part by weight of metal magnesium, at 60-110° C. in the presence of 0.001-0.2 parts by weight of a nitrogen-based halogen compound as a reaction initiator, based on 1 part by weight of metal magnesium, selected from the following (1)-(4):

(1) N-halide succinimides represented by the general formula

wherein, X is a halogen atom, and R 1 , R 2 , R 3 and R 4 are independently hydrogen, or C 1-12 alkyl or C 1-12 aryl;

(2) trihaloisocyanuric acid compounds represented by the general formula

wherein, X is a halogen atom;

(3) N-halophthalimide compounds represented by the general formula

wherein, X is a halogen atom, and R 1 , R 2 , R 3 and R 4 are independently, hydrogen, or C 1-12 alkyl or C 1-12 aryl; and

(4) hydantoin compounds represented by the general formula

wherein, X is a halogen atom, and R 1 and R 2 are independently hydrogen, or C 1-12 alkyl or C 1-12 aryl;

reacting the above obtained dialkoxy magnesium carrier with titanium tetrachloride; and

reacting the resultant product with titanium tetrachloride and an internal electron donor.

2. The method according to claim 1 , wherein the average particle diameter of the metal magnesium is 10-300 μm.

3. The method according to claim 1 , wherein the alcohol is one or more selected from aliphatic alcohols represented by ROH, wherein R is a C1-6 alkyl group, and aromatic alcohols.

4. The method according to claim 1 , wherein the internal electron donor is one or more selected from phthalic acid diesters and derivatives thereof, and benzoates and derivatives thereof.
