The present disclosure relates to an antibacterial polymer composition, more specifically, to an antibacterial polymer composition enabling preparation of a coating layer exhibiting excellent antibacterial property. The antibacterial polymer composition may use a polymer including a specific number of repeat units as an antibacterial agent. Accordingly, unlike coating compositions using antibacterial monomers/antibacterial oligomers, elution of an antibacterial agent from the coating layer may be prevented even after time passes, and thus, it can continuously exhibit antibacterial property, and yet, is difficult to be absorbed in human body.

Antibacterial polymer composition

Provided are both a superabsorbent polymer capable of continuously and safely exhibiting an improved bacterial growth inhibitory property and a deodorant property without deterioration in the physical properties of the superabsorbent polymer, such as water retention capacity, absorption under pressure, etc., as well as a preparation method for the superabsorbent polymer.
