  • Process for producing coarse-particle anion-exchanger gels
    Patent number: 6924317
    Abstract: The present invention relates to a process for producing monodisperse anion-exchanger gels with high stability, purity and coarse particle size greater than 800 ?m starting from a monodisperse bead polymer with a swelling index of from 2.5 to 7.5 and more than one subsequent feed procedure without any separation between the polymerization steps and then modifying to give the anion exchanger.
