Abstract:
Process for the production of a substituted polyazacycloalkane grafted on a solid support, said process comprising reacting:CH.sub.2.dbd.CH--R.sub.3, wherein R.sub.3 is selected from the group consisting of --COOH, --CONH.sub.2, --CH.sub.2 OH, --CN and --COOR.sub.4, R.sub.4 being an alkyl or benzl group, in the presence of a polar sovent, with a polyazacyloalkane that is grafted on a solid support, R.sub.1, and that is of formula (VII), (VIII), or (IX): ##STR24##in which n, m, p, q or r, which can be the same or different, are equal to 2 or 3 and R.sup.1 is selected from the group consisting of (i) crosslinked or non-crosslinked, organic polymer, and (ii) a silica derivative of the formula (A) or (B) so as to obtain a polyazacycloalkane grafted on a substituted, solid support of the formula (X), (XI), or (XII): ##STR25##wherein S represents a silica gel, b being between 1 and 4 and R.sub.7 is an alkyl group or a hydrogen atom ##STR26##
