Abstract

The invention relates to a modified adsorption resin and a preparation method thereof, and concretely relates to a modified adsorption resin simultaneously having a polar group and a protonatable tertiary amine group, and a preparation method thereof. The method comprises the following steps: 1, suspension polymerization balling: preparing a polystyrene resin through a routine resin preparation process; and 2, grafting reaction and residual double bond post-crosslinking: swelling the resin obtained in step 1 with an organic solvent according to a case that 6-10L of the organic solvent is needed by each kilogram of the resin, adding a polar monomer and an initiator, carrying out a stirring reaction at 60-80DEG C for 4-8h, extracting out the obtained mother liquid, washing the obtained resin with a grafting reaction solvent twice, supplementing a crosslinking reaction solvent, adding a Fourier catalyst, carrying out a stirring reaction at 60-80DEG C for 4-8h, and washing the obtained resin after reaction ending to obtain the modified adsorption resin simultaneously having a polar group and a protonatable tertiary amine group. The specific surface of the resin is increased, so the introduction of the polar group and the maintenance of a high specific surface are simultaneously realized.

Description

Technical field:

[0001] The invention belongs to the preparation technology of polymer separation materials, and relates to a modified polystyrene type adsorption resin and its preparation method, which is characterized in that the modified adsorption resin contains both polar groups and protonatable tertiary amines group. Background technique:

[0002] Porous polystyrene-stilbene cross-linked resin microspheres, as polymer adsorbents, have been more and more widely used in the fields of polymer adsorption and separation materials, chromatographic packing, enzyme immobilization, biomedicine, and cosmetics.

[0003] For polystyrene-type adsorption resins, the main components of industrial divinylbenzene, which are the raw materials for preparing adsorption resins, are: p-divinylbenzene, m-divinylbenzene, p-ethylstyrene and m-ethylstyrene, After polymerization, a cross-linked polymer network structure is obtained. Studies have shown that the content of divinylbenzene exceeds ...
