Abstract

A polymer that contains an antimicrobial, bioresistant and fungal resistant moiety that is linked into the backbone of the polymer. The moiety is a bromine atom and a nitro group linked to one or more of the carbon atoms forming the backbone. The moiety can appear in the polymer chain in various levels of occurrence from 5 ppm to has high as 100% with a normal occurrence of between 1000 ppm to 20,000 ppm. Polymer types that can be created with this moiety to display these properties include, but are not limited to, polyurethane, polyurea, polyamide, polyester, polycarbonate, polyether, polysiloxane, epoxy, polyacrylic, polyacrylate, polyvinyl.
