Abstract: Disclosed is a method of producing a propylene-based copolymer using a solid catalyst including a carrier, produced by the reaction between dialkoxy magnesium and a metal halide, a titanium halide, and an organic electron donor. According to the disclosure, it is possible to produce a propylene-based copolymer having a high comonomer content and a low amorphous content while maintaining catalyst activity at a highly level and dramatically reducing agglomeration of polymer particles during the production of the copolymer.

Abstract: Disclosed is a method for producing a solid catalyst for propylene polymerization, the method comprising steps of: (1) reacting a dialkoxy magnesium with a metal halide compound in the presence of an organic solvent; (2) reacting the reaction product of step (1) with at least one internal electron donor while increasing the reaction temperature; and (3) reacting the reaction product of step (2) with a titanium halide, wherein the dialkoxy magnesium in step (1) is produced through a reaction step of reacting metal magnesium, an alcohol, and a reaction initiator.
