  • THIOSULFATE POLYMERS
    Publication number: 20140288253
    Abstract: A thiosulfate polymer includes both an electron-accepting photosensitizer component and thiosulfate groups in the same molecule, arranged in random order along the backbone. The thiosulfate polymer composition can be formulated into compositions and 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 sequester metals in nanoparticulate form, and as a way for shaping human hair in hairdressing operations.
