1. A process for purifying impure sugar solutions, including simultaneous decolorization and clarification, comprising the steps of:

  • (a) contacting the impure sugar solution with previously isolated, submicroscopic ion exchange resin particles in the form of approximately spherical beads of crosslinked copolymer having diameters within the range from about 0.01 to about 1.5 micrometers and bearing from about 0.7 to about 1.5 anion exchange functional groups per monomer unit, and(b) separating the ion exchange resin particles from the sugar solution.
