Nano-ZrO₂@C, Nano-(ZrC, ZrO₂)@C and Nano-ZrC@C Composites Prepared by Plasma-Assisted Carbonization of Zr-Loaded Iminodiacetate-Functionalized Styrene-Divinylbenzene Copolymers

Inorganics, 2022
We have developed an easy route to prepare (nano-ZrO2,nano-ZrCx)@C composites with varying ZrO2/ZrCx content. The process consists of preparing a zirconium-loaded, iminodiacetate-functionalized styrene-divinylbenzene (STY-DVB) copolymer, and its ...

3D‐Printable Nanoporous Thermosets via Disulfide‐Based Polymerization‐Induced Microphase Separation

Angewandte Chemie, EarlyView.
α‐Lipoic acid‐derived degradable macro‐chain transfer agents (macroCTAs) with tunable hydrophilicity drive polymerization‐induced microphase separation (PIMS) in photocurable resins. Selective etching via disulfide cleavage then generates interconnected nanoporous thermosets, and compatibility with liquid‐crystal display (LCD) 3D printing enables the ...

Synthesis and Properties of Anion Exchangers Derived from Chloromethyl Styrene Codivinylbenzene and Their Use in Water Treatment

International Journal of Polymer Science, 2010
Amination of vinylbenzyl chloride-divinylbenzene (VBC-DVB) copolymers is an effective method for preparation of ion-exchange resins. Conventionally, the starting polymer is produced by chloromethylation of a styrene-divinylbenzene copolymer that utilizes

Removal of Phenol from aqueous solutions by Polymeric composites containing Ni and Co particles

Polímeros, 2013
Magnetic composites have a wide range of potential technological applications; however the evaluation of this material for extraction of phenolic compounds has not been sufficiently studied. Due to its high toxicity and solubility the removal of phenolic

Artificial stabilization of the fusion pore by intra-organelle styrene-maleic acid copolymers

, 2021
Styrene-maleic acid copolymers have become an advantageous detergent-free alternative for membrane protein isolation. Since their discovery, experimental membrane protein extraction and purification by keeping intact their lipid environment has become ...

Thermal stability of polydivinylbenzene and of copolymers of styrene with divinylbenzene and with trivinylbenzene

, 1961
Samples of polydivinylbenzene (PDVB) and of copolymers of styrene with divinylbenzene (DVB) and with trivinylbenzene (TVE) were pyrolyzed in a vacuum in the temperature range of 346 to 450 C. The volatile products were collected in two fractions: A heavy

Styrene-divinylbenzene copolymer grafted with phosphonic acid dialkyl esters

Journal of the Serbian Chemical Society, 2004
The functionalization of a crosslinked chloromethylated polystyrene 8% divinylbenzene copolymer with phosphonic ester groups is detailed. The reacton conditions were studied in order to determine the optimal conditions for obtaining only diesters. Astatistical method for the calculation of the fraction of repetive units for the inited and final resin ...
