Gel-type and macroporous 4-vinylpyridine-derived polymer resins have been prepared by suspension polymerisation employing ethylene glycol diacrylate, ethylene glycol dimethacrylate or divinylbenzene as the crosslinker. Each resin has also been converted into its pyridinium ion form via methylation using methyl iodide, in effect producing the corresponding anion exchange resins. The hydrolytic stability...
Monolithic crosslinked polymer rods ( 10 mm x 50 mm) have been prepared by polymerisation of styrene with divinylbenzene, poly(ethylene glycol) (PEG)400 diacrylate or PEG1000 diacrylate as crosslinker dissolved in a suitable solvent. Adjustment of the reaction composition allows soft but mechanically strong rods to be produced which can be readily cut into discs of 1-2.5 mm thickness. Discs with...
