The present invention provides antimicrobial polymers, composition, and methods for producing the same. The polmyeric composition comprises a polymer having a functional monomeric unit; and an antimicrobial agent attached to the functional monomeric unit. The monomeric unit preferably includes a functional group such as a carboxylate group, an alkoxide, a phosphate or aphosphonate group. The antimicrobial polymers are preferably antimicrobial textiles, which can be used in a wide variety of applications. Suitable applications include surgeon's gowns, caps, masks, surgical covers, patient drapes, carpeting, bedding material, underwear, socks sports, sportswear and healthcare uniforms.
