Acrylonitrile copolymers

Abstract

Abstract UNSHAPED OR SHAPED, CROSSLINKED COPOLYMERS WHICH COMPRISES A CARBON-CARBON LINEAR CHAIN COMPRISING RECURRING UNITS OF THE FORMULA: -CH2-CH(-CN)- AND OF FORMULA: -CH(-R1)-CH(-A-N(+)(-R2)(-R3)-)- X(-) (I) AND/OR -CH(-R1)-CH(-C5H4N(+)) X(-) (II) IN WHICH R1 REPRESENTS A HYDROGEN ATOM OR A LOWER ALKYL RADICAL; EACH OF R2 AND R3, WHICH MAY BE THE SAME OR DIFFERENT, REPRESENTS AN ALKYL RADICAL HAVING 1 TO 10 CARBON ATOMS OR R2 AND R3 TOGETHER FORM A DIVALENT ALKYLENE OR ALKENYLENE RADICAL; A REPRESENTS A DIVALENT AROMATIC OR ARYLALIPHATIC RADICAL, OR A RADICAL OF FORMULA -CO-O-(CH2)M- IN WHICH M IS A POSITIVE INTEGER, THE TERMINAL METHYLENE GROUP BEING ATTACHED TO THE NITROGEN ATOM; THE PYRIDINE NUCLEUS IS OPTIONALLY SUBSTITUTED BY ONE OR MORE HYDROCARBON RADICALS R4 HAVING AT MOST 10 CARBON ATOMS, OPTIONALLY SUBSTITUTED BY FUNCTIONAL GROUP; X REPRESENTS AN INORGANIC OR ORGANIC ANION; AND THE NITROGEN ATOMS ARE CONNECTED TO ONE ANOTHER BY POLYVALENT ORGANIC RADICALS R, ARE PROVIDED FROM WHICH MEMBRANES HAVING USEFUL ION-EXCHANGE PROPERTIES AND PERMEATION PROPERTIES CAN BE OBTAINED.
