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.

Claims (2)

1. A bromo-nitro modified polyether of the formula:

wherein R, and R′ are the same or different and are independently chosen from the groups containing: [—(CH 2 O) m —, —(CH 2 CH 2 O) n —, —(CH 2 CH(CH 3 )O) o —, —(CH 2 CH(CH 2 CH 3 )O) p —] wherein m, n, o and p are independently chosen integers between 0 and around 100 wherein m, n, o and p may not all be zero.
