Polymers with Inherent Antimicrobial Properties

Pol)nners having inherent antimicrobial or antistatic properties can be applied or used in conjimction with a wide variety of substrates 

Such properties are imparted by applying a coating or film formed from a cationically-charged polymer composition compris- 

Chitosan, modified chitosans or chitosan salts can be incorporated into the compositions. Chitosan is a naturally occurring amino-functional saccharide which is known to be antimicrobial. Moreover, chitosan could also serve the dual purpose of ako providing steric stabilization. 

Other antimicrobial agents include metal biocides such as silver, zinc, etc. and salts. Organic compounds are chlorohexidine de-rivates, dodecyl diethylenediamine glycine, phenolic compoimds, polymeric guanidines. 

Krishnan, Antimicrobial and antistatic polymers and methods of using such polymers on various substrates, US Patent 7 491753, assigned to Mallard Creek Polymers, Inc. (Chalotte, NC), February 17, 2009.
