Electrically conductive membranes and the like comprising copolymers of divinyl benzene and olefinic carboxylic compounds

Claim 1

THE METHOD OF TREATING SOLUTIONS TO REMOVE CATIONS THEREFROM WITHOUT THE SUBSTANTIAL TRANSFER OF ANIONS THERETO, COMPRISING SEPARATING SAID SOLUTION FROM A SECOND ELECTROLYTIC SOLUTION BY MEANS OF A CATION-PERMEABLE SOLID BARRIER COMPRISING AN INSOLUBLE INFUSIBLE COPOLYMERIC MATRIX CONTAINING DIVINYL BENZENE AND A MONOMER OF THE GROUP CONSISTING OF OLEFINIC CARBOXYLIC ACIDS AND THE ANHYDRIDES, ESTERS, AND ACID CHLORIDES THEREOF, IN THE PROPORTIONS OF NOT MORE THAN 8 MOLS OF CARBOXYLIC COMPOUND PER MOL OF DIVINYL BENZENE, SAID MATRIX BEING IN GEL RELATIONSHIP WITH AT LEAST 20 PER CENT OF SOLVENT BY WEIGHT, BASED ON THE WEIGHT OF POLYMER INCLUDING SOLVENT AND SAID SOLVENT PRESENTING A CONTINUOUS PHASE THROUGHOUT SAID GEL, AND PASSING A DIRECT ELECTRIC CURRENT IN SERIES THROUGH SAID SOLUTIONS AND BARRIER IN THE DIRECTION TO CAUSE THE MIGRATION OF CATIONS FROM THE FIRST SOLUTION TO THE SECOND SOLUTION.

Claim 2

THE METHOD OF TREATING SOLUTIONS TO REMOVE CATIONS THEREFROM WITHOUT THE SUBSTANTIAL TRANSFER OF ANIONS THERETO, COMPRISING SEPARATING SAID SOLUTION FROM A SECOND ELECTROLYTIC SOLUTION BY MEANS OF A CATION-PERMEABLE SOLID BARRIER COMPRISING AN INSOLUBLE INFUSIBLE COPOLYMERIC MATRIX CONTAINING DIVINYL BENZENE AND A MONOMER OF THE GROUP CONSISTING OF OLEFINIC CARBOXYLIC ACIDS AND THE ANHYDRIDES, ESTERS, AND ACID CHLORIDES THEREOF, IN THE PROPORTIONS OF NOT MORE THAN 8 MOLS OF CARBOXYLIC COMPOUND PER MOL OF DIVINYL BENZENE, SAID MATRIX BEING IN GEL RELATIONSHIP WITH AT LEAST 20 PER CENT OF SOLVENT BY WEIGHT, BASED ON THE WEIGHT OF POLYMER INCLUDING SOLVENT AND SAID SOLVENT PRESENTING A CONTINUOUS PHASE THROUGHOUT SAID GEL, AND PASSING A DIRECT ELECTRIC CURRENT IN SERIES THROUGH SAID SOLUTIONS AND BARRIER IN THE DIRECTION TO CAUSE THE MIGRATION OF CATIONS FROM THE FIRST SOLUTION TO THE SECOND SOLUTION.
