Process of making composite ion exchange resin bodies

Claim 1

A METHOD FOR MAKING A SOLID, COMPOSITE, ION EXCHANGE RESIN BODY THAT IS INSOLUBLE IN AQUEOUS MEDIA AND THAT COMPRISES THROUGHOUT A SINGLE PIECE THEREOF AN INTIMATE MIXTURE OF A SOLID, INSOLUBLE, CROSSLINKED, ORGANIC RESIN AND AN IONIZABLE, ORGANIC RESIN THAT NORMALLY IS SOLUBLE IN AQUEOUS MEDIA AND THAT IS INSOLUBILIZED BY BEING ENTRAPPED WITHIN THE BODY OF THE SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN, WHICH METHOD COMPRISES (1) FORMING AN INTIMATE MIXTURE OF A PREFORMED SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN HAVING ABSORBED THEREIN A SOLUTION OF ABOUT EQUIMOLECULAR PROPORTIONS OF MALEIC ANHYDRIDE AND STYRENE IN AN INERT ORGANIC SOLVENT (2) POLYMERIZING SAID SOLUTION OF MALEIC ANHYDRIDE AND STYRENE WHILE THUS-ABSORBED IN THE SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN STARTING MATERIAL PRESENT IN THE MIXTURE AND (3) CONVERTING SAID NON-IONIZABLE ANHYDRIDE GROUPS, WHICH ARE THEN PRESENT IN MOLECULES OF ONE OF THE RESIN COMPONENTS, INTO IONIZABLE CARBOXYL GROUPS, ONE OF THE RESINS JUST-MENTIONED THEN BEING A THUSINSOLUBILIZED IONIZABLE CARBOXYL RESIN OF A KIND THAT IS NORMALLY SOLUBLE IN AQUEOUS MEDIA.

Claim 2

A METHOD FOR MAKING A SOLID, COMPOSITE, ION EXCHANGE RESIN BODY THAT IS INSOLUBLE IN AQUEOUS MEDIA AND THAT COMPRISES THROUGHOUT A SINGLE PIECE THEREOF AN INTIMATE MIXTURE OF A SOLID, INSOLUBLE, CROSSLINKED, ORGANIC RESIN AND AN IONIZABLE, ORGANIC RESIN THAT NORMALLY IS SOLUBLE IN AQUEOUS MEDIA AND THAT IS INSOLUBILIZED BY BEING ENTRAPPED WITHIN THE BODY OF THE SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN, WHICH METHOD COMPRISES (1) FORMING AN INTIMATE MIXTURE OF A PREFORMED SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN HAVING ABSORBED THEREIN A SOLUTION OF ABOUT EQUIMOLECULAR PROPORTIONS OF MALEIC ANHYDRIDE AND STYRENE IN AN INERT ORGANIC SOLVENT (2) POLYMERIZING SAID SOLUTION OF MALEIC ANHYDRIDE AND STYRENE WHILE THUS-ABSORBED IN THE SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN STARTING MATERIAL PRESENT IN THE MIXTURE AND (3) CONVERTING SAID NON-IONIZABLE ANHYDRIDE GROUPS, WHICH ARE THEN PRESENT IN MOLECULES OF ONE OF THE RESIN COMPONENTS, INTO IONIZABLE CARBOXYL GROUPS, ONE OF THE RESINS JUST-MENTIONED THEN BEING A THUSINSOLUBILIZED IONIZABLE CARBOXYL RESIN OF A KIND THAT IS NORMALLY SOLUBLE IN AQUEOUS MEDIA.

Claim 3

A METHOD FOR MAKING A SOLID, COMPOSITE, ION EXCHANGE RESIN BODY THAT IS INSOLUBLE IN AQUEOUS MEDIA AND THAT COMPRISES THROUGHOUT A SINGLE PIECE THEREOF AN INTIMATE MIXTURE OF A SOLID, INSOLUBLE, CROSS-LINKED, ORGANIC RESIN AND AN IONIZABLE ORGANIC RESIN THAT NORMALLY IS SOLUBLE IN AQUEOUS MEDIA AND THAT IS INSOLUBILIZED BY BEING ENTRAPPED WITHIN THE BODY OF THE SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN, WHICH METHOD COMPRISES FORMING AN INTIMATE MIXTURE OF A SOLID, INSOLUBLE, NUCLEAR CHLOROMETHYLATED COPOLYMER, OF A MAJOR PROPORTION BY WEIGHT OF AT LEAST ONE MONOVINYL AROMATIC HYDROCARBON AND A MINOR PROPORTION OF DIVINYLBENZENE, HAVING AN ACRYLIC ACID-CONTAINING SOLUTION AND A POLYMERIZATION CATALYST ABSORBED THEREIN, POLYMERIZING THE ACRYLIC ACID WHILE IT IS THUS-ABSORBED, WHEREBY A SOLID, INSOLUBLE COMPOSITE RESIN BODY COMPRISING THROUGHOUT THE SAME AN INTIMATE MIXTURE OF SAID CHLOROMETHYLATED COPOLYMER AND OF AN ACRYLIC ACID POLYMER IS FORMED, AND AMINATING SAID CHLOROMETHYLATED COPOLYMER BY CAUSING THE COMPOSTIE RESIN BODY TO ABSORB AN AQUEOUS SOLUTION OF A TRIALKYLAMINE AND HEATING THE RESULTING MIXTURE, WHEREBY SAID CHLOROMETHYLATED COPOLYMER IS CONVERTED INTO A SOLID, INSOLUBLE IONIZABLE COPOLYMER COMPONENT CONTAINING QUATERNARY AMMONIUM RADICALS IN MOLECULES THEREOF AND A SOLID, INSOLUBLE, AMPHOTERIC COMPOSITE ION EXCHANGE RESIN IS OBTAINED.

Claim 4

A METHOD FOR MAKING A SOLID, COMPOSITE, ION EXCHANGE RESIN BODY THAT IS INSOLUBLE IN AQUEOUS MEDIA AND THAT COMPRISES THROUGHOUT A SINGLE PIECE THEREOF AN INTIMATE MIXTURE OF A SOLID, INSOLUBLE, CROSS-LINKED, ORGANIC RESIN AND AN IONIZABLE ORGANIC RESIN THAT NORMALLY IS SOLUBLE IN AQUEOUS MEDIA AND THAT IS INSOLUBILIZED BY BEING ENTRAPPED WITHIN THE BODY OF THE SOLID, INSOLUBLE, CROSSLINKED ORGANIC RESIN, WHICH METHOD COMPRISES FORMING AN INTIMATE MIXTURE OF A SOLID, INSOLUBLE, NUCLEAR CHLOROMETHYLATED COPOLYMER, OF A MAJOR PROPORTION BY WEIGHT OF AT LEAST ONE MONOVINYL AROMATIC HYDROCARBON AND A MINOR PROPORTION OF DIVINYLBENZENE, HAVING AN ACRYLIC ACID-CONTAINING SOLUTION AND A POLYMERIZATION CATALYST ABSORBED THEREIN, POLYMERIZING THE ACRYLIC ACID WHILE IT IS THUS-ABSORBED, WHEREBY A SOLID, INSOLUBLE COMPOSITE RESIN BODY COMPRISING THROUGHOUT THE SAME AN INTIMATE MIXTURE OF SAID CHLOROMETHYLATED COPOLYMER AND OF AN ACRYLIC ACID POLYMER IS FORMED, AND AMINATING SAID CHLOROMETHYLATED COPOLYMER BY CAUSING THE COMPOSTIE RESIN BODY TO ABSORB AN AQUEOUS SOLUTION OF A TRIALKYLAMINE AND HEATING THE RESULTING MIXTURE, WHEREBY SAID CHLOROMETHYLATED COPOLYMER IS CONVERTED INTO A SOLID, INSOLUBLE IONIZABLE COPOLYMER COMPONENT CONTAINING QUATERNARY AMMONIUM RADICALS IN MOLECULES THEREOF AND A SOLID, INSOLUBLE, AMPHOTERIC COMPOSITE ION EXCHANGE RESIN IS OBTAINED.
