Chloromethylated polystyrene resin was chemically modified with ethylenediamine, diethylenetnamine and triethylenetetramine to polystyrene-polyamine resins (I -III). The latter resins were further reacted with two formylsalicylic acid isomers, 3-formylsalicylic acid and 5-formylsalicylic acid, to produce the cross-linking polystyrene-polyamineformylsalicylic acid resins (IV -IX). The possible chemical structure of! -IX was confirmed from the elemental analysis and FT-IR studies. Thedoi:10.2116/analsci.13.765 fatcat:bkmkgonoqzbnjpsal7qicuv7my
