Styrene-based resin adsorbent for removing high β2 microglobulin from blood

Abstract

The invention discloses a styrene resin adsorbent of new structure for removing AIDS (Acquired Immune Deficiency Syndrome) virus molecules in blood. A styrene resin of a new structure of which the aperture is 0-200nm comprises no less than 60% of the resin of which the particular size is 100-200nm. When the styrene resin adsorbent is used for a blood perfusion device as an adsorbent, a functional group of a counterpoint valence state and the resin of proper apertures are selected to fill the blood perfusion device according to the valence state property and particle size of the AIDS virus modules absorbed.

Description

technical field

[0001] The invention relates to a styrene resin, especially a modified product including styrene-divinylbenzene and styrene anion exchange resin, a preparation method and application of the product. Background technique

[0002] Styrene resins in the prior art, including styrene-divinylbenzene, styrene anion exchange resins, etc., have been widely used as adsorbents and ion exchangers.

[0003] Use metal compounds such as FeCl 3 As a catalyst for the post-crosslinking reaction of styrene-based resins, it is a conventional technology. However, all the functional modification or modification of styrene-based resins in the prior art so far have not involved improving the constituent substances or elements of the carbon chain skeleton of the resin, nor have they involved catalysts in post-crosslinking reactions. Then enter the report inside the resin structure. In the reports of the prior art, after the post-crosslinking reaction, the post-crosslinking reactio...

[0007] The purpose of the present invention is to propose a technical proposal for a new structure product, a preparation method and an application of the styrene-based resin. By changing the material structure of styrene-based resins, including: styrene-divinylbenzene resin, and styrene-based macroporous anion exchange resins and gel-type anion exchange resins, it is more suitable for use as blood purification adsorbents A new feature for in-vivo blood purification and dynamic sampling from in-vivo blood.

[0008] The present invention comprises three parts:

[0009] The first is: a new structural product of styrene-based resin, that is, a modified styrene-divinylbenzene macroporous adsorption resin, and its preparation method.

[0010] The new structure product is to embed metal element X on the carbon chain of styrene-divinylbenzene resin skeleton with network structure, and its structural formula is C-X-C; where C is carbon element, and X element is a metal element with p...
