[Problem] To provide a method for efficiently producing a poly(ethylene glycol)-b-poly(halomethylstyrene), a novel poly(ethylene glycol)-b-poly(halomethylstyrene) produced using the method, and a derivative thereof.

[Solution] The target novel copolymer can be provided by introducing a functional group, which enables reversible addition-fragmentation chain transfer (RAFT) polymerization, to the ω terminal of poly(ethylene glycol) and copolymerizing the resulting poly(ethylene glycol) with a halomethylstyrene.

Embodiments of the present invention provide for anion exchange membranes and processes for their manufacture. The anion exchange membranes described herein are made the polymerization product of at least one functional monomer comprising a tertiary amine which is reacted with a quaternizing agent in the polymerization process.

The present disclosed are a high exchange-capacity anion exchange resin with dual functional-groups and method of synthesis thereof. The invention relates to the field of environmental function material synthesis and application. The resin is based on chloromethylated polystyrene-divinylbenzene polymer as matrix, and by primary amination and quaternization, yields an anion exchange resin with dual functional-groups having both a weak base anionic group and a strong base anionic group. The anion exchange resin not only has high adsorption capacity for water-born nitrate ions, but also can effectively squelch natural organic acids such as phytic acid in water, thus simultaneously removing nitrate ions and phytic acid organic matter from water. Therefore, the resin has a broad application potential in the fields of drinking water treatment, groundwater remediation, and advanced urban sewage treatment.
