Novel biocidal N-halamine plastic based on poly(vinyl chloride): Preparation and characteristics
E-mail:
Preparation method of new biocidal plastics based on plasticized PVC has been elaborated. The
derivative of poly(4-vinylbenzyl chloride) containing N-halamine substituents has been mixed with PVC granules and processed by dry blend extrusion and injection moulding. The properties of obtained material have been tested using SEM/EDX and thermogravimetry. The biocidal efficacy of modified PVC resin has been tested against two strains of bacteria: Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive). It was found that even small amount of biocidal component yields to efficient biocidal activity of the whole plastic. Chemical composition and other properties of PVC remain almost unchanged.
