Preparação de copolímeros à base de 2-vinilpiridina com propriedades bactericidas
Química Nova, 2011 We report the development of two copolymers based on 2-vinylpyridine, styrene and divinylbenzene (2Vpy-Sty-DVB) with different porosity degrees. The copolymers were subsequently quaternized with methyl iodide.

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

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 ...

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
