摘 要:The chloromethyl groups have been introduced into commercial S/DVB copolymer matrixes via interpenetratingpolymer networks (IPN) synthesis. The procedure involves impregnation of the Amberlite XAD-4 adsorbent,with use of the vinylbenzyl chloride (VBC) and divinylbenzene (DVB) monomers mixture, and suspensionpolymerization process. The syntheses were evaluated by FT-IR spectra and SEM analyses and furthermore bychlorine content determination as well as characterization of porous structure by nitrogen adsorption at liquid nitrogentemperature. Designed synthesis approach allowed determining organic and water phases composition. Furthermore,impact of an excess of the organic phase removal method has been investigated. Basing on the obtainedresults it could be stated that the chloromethyl groups, derived from VBC monomer, were successfully introducedinto the XAD-4 structure. Captured SEM images revealed significant changes in the beads’ surface morphology afterpolymerization processes. The presented studies reveal designed and executed synthesis processes, which involvethe use of a proper water phase and excess of organic phase removal. Observed changes in the beads’ morphologysuggest that introduced functionalities are concentrated on the porous surface of the XAD-4 adsorbent.
