Document Type and Number:
Japanese Patent JP3147389
Kind Code:
B2
Abstract:
PURPOSE:To enhance the heat resistance of an exchanger by forming a cross- linked anion exchanger derived from the structural unit having a specific quaternary ammonium group and a cross-linking monomer containing unsaturated hydrocarbon group. CONSTITUTION:After forming a cross-linked copolymer using the cross-linking monomer containing unsaturated hydrocarbon group, an ammonium group is introduced into the position of -R-Z of the structural unit represented by the formula I wherein R represents 3-18C polymethylene group (contg. cyclic hydrocarbon) and Z represents group having active substituent such as bromine and chloride. As a result, is obtained a cross-linked anion exchanger containing the structural unit having the quaternary ammonium group represented by the formula II wherein R is the same as in the formula I, R1, R2 and R3 each represent 1-8C hydrocarbon and alkanol group and X represents anion and the unit derived from the cross-linking monomer containing unsaturated hydrocarbon group. The anion exchanger group of this exchanger accounts for at least 90% of the group represented by -R-N<+>R1R2R3.X<-> in the formula II.
