Problems solved by technology

However, it remains a great challenge to prepare hypercrosslinked microporous polymer materials that can be dissolved and processed with enhanced processability through streamlined techniques.
[0003] At present, the problems of traditional hypercrosslinked porous polymer materials are mainly reflected in the poor monodispersity of the material and the large size of the material, which makes it difficult to apply in specific fields.
Tan Bien et al. prepared nanomaterials with a diameter of 131-360 nm by adjusting the content of emulsifiers through classic cross-linking. However, the main components of this nanomaterial are chlorinated styrene and divinylbenzene, which do not contain F...

Abstract

The invention relates to a super-crosslinked porous polymer material capable of being dissolved and processed and a preparation method thereof. The unit structural formula of the material is shown in the specification. In the preparation process, a halogenated aromatic compound is used as a raw material, the super-crosslinked porous polymer is obtained through Friedel-Crafts alkylation, unreacted halomethyl groups remain in the finally obtained material, and the groups can be continuously subjected to Friedel-Crafts alkylation reaction to graft polymer chains; the grafted polymer can be dissolved in solvents such as N-methyl pyrrolidone, N, N-dimethylformamide or dimethyl sulfoxide, so that the novel material has the property of dissolvable processing; according to the invention, the dispersibility of the material in a polymer matrix and the compatibility of two-phase interfaces are enhanced, so that the interface defects are reduced, and the material has good application and development prospects in the aspect of gas separation membranes.
