Abstract
Poly(ethylene-co-vinyl acetate) with 55 wt % vi- nyl acetate units (EVA55) was cryogenically ground and saponified in KOH/ethanol solution to obtain poly(ethyl- ene-co-vinyl alcohol) (EVOH55). Polymeric antimicrobial agents were synthesized by reacting three antimicrobial agents, 4-aminobenzoic acid (ABA), salicylic acid (SA), and 4-hydroxy benzoic acid (HBA) with EVOH55. The polymers became more flexible and exhibited lower melting peak temperature and heat of fusion as the content of the chem- ically bound ABA, SA, and HBA units increased. These phenomena appeared more significant in the order of ABA HBA SA. S. aureus, Gram-positive bacterium, was more susceptible to the polymeric antimicrobial agents than P. aeruginesa, Gram-positive bacterium. The antimicrobial ac- tivity increased in the order of EVOH55-HBA EVOH55- ABA EVOH-SA. © 2004 Wiley Periodicals, Inc. J Appl Polym Sci 93: 765-770, 2004
