Abstract
Abstract A polymer suitable for use in affinity chromatography comprising a polymer of an aminimide and a vinyl compound having at least one pendant halo-methyl group and the said polymer wherein an amine ligand which affords sites for binding in affinity chromatography is coupled to the polymer by reaction with a portion of the pendant halo-methyl groups and the remainder of said pendant halo-methyl groups are reacted with an amine containing a pendant hydrophilic group.
