Abstract
The process includes the reaction of a chloro-formamidinium chloride with a polystyrene-divinylbenzene resin functionalized with primary amine groups. The resins which can be obtained according to this process may in particular have a spacer arm of general formula (IV): ##STR1## with X representing oxygen or sulphur and m being equal to 1 or 2. This spacer arm bears at its end, on the right, a primary amine group or a guanidine group.
