The macroporous polymeric adsorbents have been widely applied in separation and purification of natural products due to its structure is easy to control

adsorption selectivity is high

and its use is renewable. In this article

the several research progresses for synthesis and application of the polymeric adsorbent was reviewed

mainly divided into two aspects: (1) Structure of the polymeric adsorbent matrix was designed base on the synergistic effect of multiple weak interactions

such as hydrogen bonding interaction

electrostatic interaction

dipolar interaction

and so on. Meanwhile

the hydrophobic skeleton of the adsorbent was also controlled purposely according to the structure characteristic of the adsorbates. This adsorbent can be used to prepare the high purity extract of the special active component in natural product

even to separate the monomer components in one kind of effective principle. (2) Controlling of the pore structure of the adsorbent mainly focus on the pore formed method. In order to get the narrow distribution of the pore diameter of the adsorbent

the traditional non-solvating pore formed method was changed to post crosslink of methylene between the initial structures of the polystyrene adsorbent based on the Friedel-Craft Alkylation reaction. As the result

this kind of adsorbent should exhibit the double function of adsorption and sieving effect.
