Ionic polymers

Abstract

Abstract SHAPED OR UNSHAPED IONIC POLYMERS ARE PROVIDED WHICH COMPRISE RECURRING UNITS OF FORMULA -O-E-O-CH(-R)-C(-R1)(-O-(C(-R2)(-A)-C(-R3)(-B)-O)X-H)-CH2- ALONE OR WHICH RECURRING UNITS OF FORMULA -O-E-O-CH(-R)-C(-R1)(-OH)-CH2- AND/OR FORMULA -O-E-O-CH(-R)-C(-R1)(-O-(CH2(-A'')-C(-R3)(-B'')-O)Y-H)-CH2- IN WHICH EACH OF R, R1, R2 AND R3, WHICH MAY BE THE SAME OR DIFFERENT, REPRESENTS A HYDROGEN ATOM OR A METHYL RADICAL, E REPRESENTS A DIVALENT RADICAL DERIVED BY REMOVING THE PHENOLIC OH GROUPS FROM A POLYNUCLEAR DIPHENOL IN WHICH THE HYDROXYL GROUPS ARE ATTACHED TO DIFFERENT NUCLEI, X AND Y ARE POSITIVE NUMBERS, ONE OF A AND B REPRESENTS A HYDROGEN ATOM AND THE OTHER REPRESENTS A RADICAL OF FORMULA -CH2-N(+)(-R'')2-R'' Y(-) IN WHICH Y$ IS AN ANION AND EACH OF THE SYMBOLS R'', WHICH MAY BE THE SAME OR DIFFERENT, REPRESENTS A MONOVALENT OR DIVALENT ORGANIC RADICAL, OR AT LEAST TWO OF THE RADICALS TOGETHER FORM A SINGLE DIVALENT OR TRIVALENT RADICAL, ALL THE VALENCIES CARRIED BY THE R'' GROUPS BEING SATISFIED BY NITROGEN ATOMS OF GROUPS -CH2-N$, AND ONE OF A'' AND B'' REPRESENTS A HYDROGEN ATOM AND THE OTHER REPRESENTS THE -CH2X GROUP, WHEREIN X IS A HALOGEN ATOM. THESE POLYMERS HAVE UTILITY IS ANTI-STATIC AGENTS, IN IMPROVIDING THE DYE AFFINITY OF NATURAL AND SYNTHETIC POLYMERS AND AN ION-EXCHANGE MEMBRANES.
