  • Patent number: 9499650
    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.

  • Patent number: 9371423
    Abstract: The present disclosure generally provides methods and apparatus for efficiently crosslinking silicon carbide fiber precursor polymers with electron beam radiation. The methods and apparatus utilize a platform containing silicon carbide fiber precursor polymer. The temperature of the platform is regulated while the silicon carbide fiber precursor polymer is irradiated to thereby regulate the temperature of the irradiated silicon carbide fiber precursor polymer thereon. In this way, the temperature of the irradiated silicon carbide fiber precursor polymer is regulated via the platform both during and after it is subjected to radiation. At least one of the platform and the e-beam radiation mechanism may be translated with respect to the other to irradiate different portions of the silicon carbide fiber precursor polymer and, ultimately, the entirety of the silicon carbide fiber precursor polymer contained on the platform.

  • Patent number: 9359458
    Abstract: The polyzwitterionic acid antiscalant is an antiscalant for use in desalination plants and the like for inhibiting CaSO4 and SO42? scale precipitation. The polyzwitterionic acid (PZA) antiscalant has the following structural formula: In order to make the PZA antiscalant, N-carboethoxymethyl-3-(N,N-diallylamino)propanesulfonate, a zwitterionic monomer, is cyclopolymerized in aqueous solution using tert-butyl hydroperoxide (TBHP) to make an intermediate polyzwitterion (PZ). Acidic hydrolysis of the ester groups of the PZ is performed to produce the PZA antiscalant. Evaluation of the antiscalant properties of the PZA antiscalant using concentrated brines revealed that the PZA antiscalant, at a concentration of 10 ppm, is very effective in inhibiting the formation of calcium sulfate scale, particularly in reverse osmosis plants.
