<p>Polymer matrix comprising weak base functionalities wherein said weak base functionalities are attached to said polymer matrix through a nitrogen atom of a 1,X-polyaminoalkylene amine functionality, where X is an integer greater than 2 wherein said 1,X-polyaminoalkyleneamine is represented by general formula (I), wherein R is independently hydrogen, alkyl, alkylene amine, alkylene hydroxide or alkylene sulfide, a is an integer greater than 2 when b is at least one; and if b is greater than 1, a is greater than or equal to 2 with at least one of a being greater than 2. The invention also concerns a process for the preparation of these compositions by contacting a polymer matrix having haloalkyl functionalities with the above 1,X-polyaminoalkyleneamine in the presence of a solvent in an amount of from 0 to 20 times that of the volumes of the polyaminoalkyleneamine at a temperature of from 0oC to 1500C. The compositions are useful as ion exchange resins which have high anion exchange capacity as well as high resistance to oxidation.</p> |
