Provided is a mixing system to mix different types of fluids more efficiently. The mixing system installed in a piping in which a first fluid is supplied includes a mixing part including a plurality of mixing members each having a front end and a rear end rotated by a predetermined angle to form a curved surface and disposed to be spaced apart from each other and a supply part supplying a second fluid to a space between adjacent mixing members.

Mixing system

Provided are a metal-ligand complex, a catalyst composition for ethylene-based polymerization including the same, and a method for preparing an ethylene-based polymer using the same. Since the metal-ligand complex of the present invention in which a certain functional group is introduced to a certain position has high solubility and catalytic activity, the catalyst composition comprising the same for ethylene-based polymerization including the same may produce an ethylene-based polymer having excellent physical properties.
