Thermal stability anion exchanger

摘要

PROBLEM TO BE SOLVED: To provide a heat-stable anion exchanger, and to provide its manufacturing method and usage.;SOLUTION: The anion exchanger is an anion exchanger based on an aromatic monomer having a structure of general formula (I) and a cross-linking agent, and also having a resistance at least at a working temperature of 60°C over comparatively a long time in an OH form. In the formula, Ak, Ak' and Ak'' are each mutually independently the same or different 1-18C alkyl group; n is an even number between 5-18; x+y=2; and X is Cl, Br, OH, HCO₃, HSO₄, 1/2(SO₄), 1/2CO₃, NO₃, F, H₂PO₄, 1/2HPO₄ and 1/3PO₄.;COPYRIGHT: (C)2008,JPO&INPIT
