Claim 1

A FLUID PURIFICATION MATERIAL WHICH IS A SUBSTANTIALLY WATER AND DILUTE ACID INSOLUBLE, GRANULAR, CURED RESIN AND WHICH CONSISTS OF AN ALKYLENE POLYAMINE-FORMALDEHYDE CONDENSATION PRODUCT WHEREIN THE AMINO GROUPS OF THE POLYAMINE ARE CONNECTED BY ALIPHATIC LINKAGES, THE AMINO GROUPS OF SAID POLYAMINE HAVING AT LEAST ONE HYDROGEN ATTACHED TO EACH AMINO GROUP PRIOR TO CONDENSATION WITH FORMALEDHYDE, SAID CONDENSATION PRODUCT NORMALLY HAVING SUBSTANTIAL WATER AND DILUTE ACID SOLUBILITY BUT BEING INSOLUBILIZED BY INTERPOLYMERIZATION WITH A FORMALDEHYDE CONDENSATION PRODUCT OF AN AMINOTRIAZINE HAVING 2 TO 6 HYDROGEN ATOMS BOUND TO AMINO NITROGEN ATACHED TO THE TRIAZINE RING, SAID INSOLUBLE RESIN BEING ESSENTIALLY A FORMALDEHYDE CONDENSATION PRODUCT OF ALKYLENE POLYAMINE AND AMINOTRIAZINE IN WHICH THE MOLAR RATIO OF ALKYLENE POLYAMINE TO AMINOTRIAZLINE IS FROM ABOUT 1:1 TO 1:4 AND WHICH CONTAINS 0.5 MOL OF FORMALDEHYDE FOR EACH MOL OF HYDROGEN ATTACHED TO AMINO NITROGEN IN SAID ALKYLENE POLYAMINE AND IN SAID AMINOTRIAZINE.
