Branched polymeric media: boron-chelating resins from hyperbranched polyethylenimine.
Extraction of boron from aqueous solutions using selective resins is important in a variety of applications including desalination, ultrapure water production, and nuclear power generation. Today's commercial boron-selective resins are exclusively prepared by functionalization of styrene-divinylbenzene (STY-DVB) beads with N-methylglucamine to produce resins with boron-chelating groups. However...
متن کاملBranched polymeric media: perchlorate-selective resins from hyperbranched polyethyleneimine.
Perchlorate (ClO(4)(-)) is a persistent contaminant found in drinking groundwater sources in the United States. Ion exchange (IX) with selective and disposable resins based on cross-linked styrene divinylbenzene (STY-DVB) beads is currently the most commonly utilized process for removing low concentrations of ClO(4)(-) (10-100 ppb) from contaminated drinking water sources. However, due to the l...
متن کاملA novel photodegradable hyperbranched polymeric photoresist.
We report the first synthesis of a photodegradable hyperbranched polyacetal, wherein every repeat unit carries a photo-labile 2-nitrobenzyloxy moiety. The pristine HBP serves as a positive photoresist to create micron-size patterns; furthermore, by changing the terminal groups to dipropargyl acetal, clickable photo-patterned substrates can be generated.
متن کاملChipal Chelating Resins in Chromatogpaphy of Optical Isomers
The ways of binding optically active ligands, mainly of the amino acid type, to cross—linked polymers of styrene, acrylamide or glycidylmethacrylate are reviewed. When coordina— ted to transition metal ions, these polymers display a high discriminating ability in sorption of optical isomers of corn— pounds capable of forming mixed—ligand complexes. The kinetic performance of the ligand—exchangi...
متن کاملThermo-/pH-dual responsive properties of hyperbranched polyethylenimine grafted by phenylalanine
Novel thermo- and pH-dual responsive amphiphilic copolymers were synthesized based on hyperbranched polyethylenimine (PEI) by grafting L-phenylalanine. The phenylalanine-modified PEI exhibited lower cytotoxicity than commercial PEI. These copolymers showed the phenomena of phase transitions in response to pH and temperature. The dilute copolymer solution at lower pH displayed the higher LCST. F...
