ABSTRACT:
An ion exchange resin bed capable of hydraulic segregation into discrete zones of ion exchange resins having different ion exchange functionalities, the resins being produced by functionalizing fractions of a single batch or lot of precursor copolymer which have been segregated on the basis of differing hydraulic densities of the different sized particles, and the method for producing the same.
