Abstract
Official abstract text for this publication.
A thiosulfate polymer composition includes an electron-accepting photosensitizer component, either as a separate compound or as an attachment to the thiosulfate polymer. The thiosulfate polymer composition can be applied to various articles, or used to form a predetermined polymeric pattern after photothermal reaction to form crosslinked disulfide bonds, removing non-crosslinked polymer, and reaction with a disulfide-reactive material. Such thiosulfate polymer compositions can also be used to sequestering metals.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of sequestering metal in a polymeric composition, the method comprising: providing a polymeric layer comprising a non-crosslinked thiosulfate polymer that also comprises pendant organic charged groups, photochemically reacting the non-crosslinked thiosulfate polymer to provide polymer layer areas comprising a crosslinked polymer having disulfide groups in a predetermined pattern in the polymeric layer, and polymeric layer areas outside the p…
