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.
