Abstract
Methods of making macroporous anion exchange resins are described. The macroporous anion exchange resins are in the form of particles such as beads that contain a hydrophilic, crosslinked, (meth)acrylic-type polymeric material. Additionally, methods of purifying a negatively charged material using the macroporous anion exchange resins, methods of making chromatographic columns that contain the macroporous anion exchange resins, methods of making filter elements that contain the macroporous anion exchange resins, and methods of making porous composite materials that contain the macroporous anion exchange resins are described.
