摘要：A process for the preparation of an anion exchange resin is described, which comprises reacting an aromatic crosslinked haloalkyl-containing copolymer with an amine in the presence of at least 100 parts by weight, per 100 parts by weight of the copolymer, of water and at least 5 parts by weight, per 100 parts by weight of water, of a water-soluble inorganic salt. A process for the preparation of an anion exchange resin is also described, which comprises acting a haloalkylating agent on an aromatic crosslinked copolymer, separating an unreacted portion of the haloalkylating agent from the aromatic crosslinked haloalkyl-containing copolymer so obtained, and reacting the resulting haloalkyl-containing copolymer with an amine in the presence of at least 100 parts by weight, per 100 parts by weight of the copolymer, of water and at least 5 parts by weight, per 100 parts by weight of water, of a water-soluble inorganic salt.
