  • Publication number: 20190300389
    Abstract: A cross-linked polymeric resin which contains reacted monomer units of an aniline, a diaminoalkane, and an aldehyde, and which is functionalized with at least one dithiocarbamate moiety. A process for producing the cross-linked polymeric resin whereby an aniline and a diaminoalkane are linked together by Mannich-type polycondensation reactions with an aldehyde. The resulting Mannich-type polycondensation product is converted into the cross-linked polymeric resin through functionalization of one or more amine functional groups with dithiocarbamate moieties. A method for removing heavy metals, such as Hg(II), from an aqueous solution, whereby the cross-linked polymeric resin is contacted with the aqueous solution, and the heavy metal is thus adsorbed onto the cross-linked polymeric resin.

  • Patent number: 10388809
    Abstract: A method of treating a polycarbonate glass surface, such as a bisphenol A polycarbonate, whereby the glass surface is immersed in a liquid phase polar aprotic solvent, such as dichloromethane, and exposed to a vapor phase polar aprotic solvent, such as acetone thus obtaining a textured glass surface with a hierarchical patterned nanoporous structure wherein the textured glass surface has a higher surface hydrophobicity and a marginally reduced optical light transmittance relative to the polycarbonate glass surface prior to the immersion, the exposure, or both.
