ABSTRACT:
A process for preparing anion exchange resin having macroreticular structure by suspension copolymerizing a polyvinylidene crosslinking monomer and a monoethylenically unsaturated aliphatic ester of acrylic acid in the presence of a liquid which is substantially immiscible with the aqueous phase of the suspension polymerization medium, which is a solvent for the monomers, and which does not substantially swell the resulting copolymer; the resulting macroreticular copolymer is isolated and aminolyzed to form an anion exchanger.
