METHOD FOR PREPARING RESINS HAVING A PRIMARY AMINE OR GUANIDINE FUNCTION, AND RESULTING RESINS

摘要

A method wherein a chloroformamidinium chloride is reacted with a polystyrene-divinylbenzene resin functionalised by primary amine groups is disclosed. The resins produced according to the method may particularly have a spacer arm of general formula (IV): -CH2-(-X-CH2-CH2-)m-, where X is oxygen or sulphur and m is 1 or 2. Said spacer arm has a primary amine group or guanidine group at its right-hand end.
