Abstract

Hypercrosslinked networks with quarternary pyridinium groups have been prepared by
N-alkylation of mono-4-vinylpyridine (4-VP) or poly-4-VP with polyfunctional reagents such as 1,4-bis-
(halomethyl)-benzenes and 4-vinylbenzylchloride using thermodynamically good solvents as reaction
medium. This type of strong basic anion exchangers with high density of positive charge and high
accessibility of the sorption sites are effective in sorbing complex salts of platinum group metals from
mineral acid solutions.
