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.
Claims7
A process for adsorbing proteins onto a copolymer functionalized with functional groups having an affinity for proteins which comprises contacting the proteins with the functionalized copolymer in the form of crosslinked, macroporous, spherical copolymer beads having a particle size between about 10 .mu.m and about 2 mm, the copolymer being predominantly poly(methacrylic anhydride).
