US 9,527,918 B2 · Antibacterial polymers and method for obtaining the same

Abstract

The invention relates to polymers selected from among polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), polyvinylchloride (PVC) and polyethylene terephthalate (PET), nylon and polystyrene, having antibacterial properties, wherein the antibacterial effect is obtained by adding a zinc salt selected from among: zinc PCA, zinc oxide, zinc hydroxide, zinc pyrrolidone or zinc pyrithione during the process of polymerization of the monomers. The antibacterial polymers are used to prepare products intended to enter into contact with the skin.

Claims5

Dependent claims

An antibacterial thermoplastic polymer, said antibacterial thermoplastic polymer being polyethylene terephthalate (PET) obtainable from a process comprising the steps of:

a) solubilizing zinc PCA in at least an organic and/or aqueous solvent;
b) adding the solution thus obtained to a solution or dispersion of at least one monomer in an organic and/or aqueous solvent;
c) polymerizing the at least one monomer,
wherein the zinc PCA is dispersed within the polymeric structure, imparting antiseptic properties to the polymer, wherein said zinc PCA is 2-5 weight percent of said polymer.
