The invention belonging to the technical field of material chemistry relates to a polydivinylbenzene material with a super strong absorption characteristic and a synthesis method, in particular to a mesoporous polymer in which polymeric chains loose enlace polydivinylbenzene as a framework, the specific surface area is 200 to 700 m 2/g, the water absorption capability is nearly 2.0 g/g, and the liquid absorption capability reaches 17 g/g. Divinylbenzene monomers are dispersed into organic solution, which is then added with azobisisobutyronitrile as initiator, after stirring, the solution is poured into a reaction kettle, and the mesoporous polymer material is synthesized by a solvent thermal process. The method of the invention avoids the traditional step of removing template agent in the synthesis of mesoporous materials, and the size of mesopore can be regulated by selecting different solution. The synthesis process is simple, requirement is low, and cost is low. The mesoporous polymer of the invention can be widely applied to absorbing organic pollutants, treating pollution caused by the leakage of organic matters.
