Abstract
An antibacterial polymer having a molecular weight above a certain level, which is highly miscible with other polymers compared to a monomolecular type antibacterial agent and can be added during the melt extrusion process. Further the antibacterial polymer has the advantage of exhibiting excellent antibacterial properties against Gram-negative bacteria and does not elute over time.
