Biostatic and biocidal activities of water-thinnable polyesteramide compositions containing 8-hydroxyquinoline

Various water soluble polyesteramide compositions are prepared by solvent technique containing a stoichiometric amount of 8-hydroxyquinoline as preservative against microbiological attack. Mechanism of action of 8-hydroxyquinoline against Pseudomonas aeruginosa ATCC 10145 is discussed and the studies showed promising results as biostatic and biocidal coatings. Preparation of water soluble polyesteramides via solvent process by using a new technique is another aspect taken into consideration.
