Aminated ion exchange resins and production methods thereof

摘要

This invention relates to certain novel anion exchange resins and methods of making them. It relates more particularly to aminated cross-linked resin bead polymers containing an inert and/or chloromethylated core, and an aminated outer shell, and to methods for preparing the same. These resins exhibit improved anion exchange properties.

主权项

1. Anion exchange resin in bead form, comprising:
aminated functional groups; and a matrix of a cross-linked polymer containing a core area and a shell area,wherein the concentration of aminated functional groups is lower in the core area relative to the shell area.
