Thermal Crosslinking of a Chemically-Modified Ionomer

  • Chapter
Polymeric Separation Media

Part of the book series: Polymer Science and Technology ((POLS,volume 16))

Abstract

Perfluorosulfonic acid ionomer resins have received considerable attention by the chlor-alkali industry as chemically inert polymers suitable for use as cation exchange membranes in sodium chloride electrolysis cells. A paper by Hora and Maloney1 reported that the low cation selectivity of standard perfluorosulfonic acid membranes is improved by amine modification of the sulfonyl halide form with ethylenediamine (EDA). Several related patents2 describe this reaction and its consequences on membrane selectivity. In addition to direct amidation, the patents refer to the process of post heat treatment which results in crosslinking by the difunctional amine. This paper summarizes an investigation of the chemistry of this thermal crosslinking reaction.
