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

Sorption of phenanthrene by crosslinked polymers with varied monomeric compositions [PDF]
PolímerosSolid-phase extraction is an efficient strategy for preconcentrating several analytes. Studies of the relationship between the monomeric composition of polymers and sorption capacity of polycyclic aromatic hydrocarbons (PAHs) need to be expanded, seeking

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

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 ...

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption
Journal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.
