Abstract
Suspension-polymerized, crosslinked copolymers of methacrylic anhydride yield beads suitable as precursors for weak-acid and other ion exchange resins, affinity chromatography materials and other materials which require spherical polymers having reactive anhydride groups for their preparation. Both gel and macroporous beads of these copolymers may be made by the process of the invention.
