The present invention relates to a polymer compound used as a polymer modifier, a conjugated diene-based polymer including a functional group derived therefrom, and a method for preparing a modified and conjugated diene-based polymer using the polymer compound. A rubber modifier compound obtained therefrom is used as a modifier for rubber, particularly, as a modifier of a conjugated diene-based polymer and is bonded to a chain of the conjugated diene-based polymer to easily introduce a functional group having affinity with a filler.

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.
