ABSTRACT:
Hybrid copolymers are prepared by at least partially filling the macropores of a macroreticular copolymer with a guest crosslinked copolymer of either the same monomers or a copolymer of different type monomers. The hybrid copolymers can be readily converted into ion exchange resins. Such resins have markedly improved physical and chemical properties, including improved ion exchange properties.
