Colored inert material for separation of anion and cation resin components. Ziarkowski, Stanley M.; Burke, James M. (Sybron Corp., USA). U.S. US 4473664 A 25 Sep 1984, 3 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: B01J001-09. NCL: 521028000. APPLICATION: US 83-515709 20 Jul 1983. DOCUMENT TYPE: Patent CA Section: 61 (Water) Section cross-reference(s): 38 An inert polymer in bead form which has been dyed with a highly visible bright color and which has a settling velocity between that of the cation exchanger and that of the anion exchanger in a mixed bed (for water purifn.) serves as a visible barrier between the 2 exchangers in the system during backwashing. Thus, a (dimethylamino)ethyl methacrylate-divinylbenzene-Me methacrylate copolymer [94062-86-9] was prepd. and dyed with Oil Sol. Blue A [14233-37-5] to give crosslinked inert beads with max. operating temp. 100°, screen size 16-30 mesh (wet), operating pH range 0-14, insoly. in all common solvents, and sp. gr. 1.15.
