Title:
熱安定性アニオン交換体
Document Type and Number:
Japanese Patent JP4744494
Kind Code:
B2
Abstract:
Crosslinked anion exchange resins based on polystyrene substituted in position 4 with cationic trialkylammonio-alkyl-aminomethyl groups. Anion exchange resins based on aromatic monomers and crosslinkers, containing structural units of formula (I). Ak, Ak', Ak" : 1-18C alkyl; n : an even number between 5 and 18; (x+y) : 2; X : Cl, Br, OH, HCO 3, HSO 4, 1/2 (SO 4), 1/2 (CO 3), NO 3, F, H 2PO 4, 1/2 (HPO 4) or 1/3 (PO 4) . An independent claim is included for a method for the production of heat-stable anion exchange resins as above by alkylating amino group-containing bead polymers or polymerising alkylated, amino group-containing monomers and converting the product into the ionic form by transferring charge.
