ABSTRACT:
A process for producing an ion exchange resin having a specific surface area of at least 0.04 m.sup.2 /g, an ion exchange resin produced by the process, and a method for removing ionic and noinionic impurities from a condensate by means of the ion exchange resin produced by the process. The process comprises the steps of: (1) uniformly imbibing a monomer mixture comprising a bifunctional unsaturated aromatic monomer and a monofunctional unsaturated aromatic monomer into aromatic crosslinked copolymer particles comprising a monofunctional unsaturated aromatic monomer and a bifunctional unsaturated aromatic monomer and having a porosity of not more than 0.2 ml/g; (2) polymerizing the monomer mixture in the presence of a polymerization initiator; and (3) introducing an ion exchange group into the resulting copolymer particles. The ion exchange resin has a large specific surface area and high physical strength and is capable of removing both ionic and noinionic impurities from a condensate.
