Abstract
The synthesis of porous polymeric materials with a high proportion of micropores, including ultramicropores, from a multifunctional branched monomer by the Ni-catalyzed cyclotrimerization reaction followed by heat treatment at 500°C is presented. The textural surface properties of these polymeric materials have been studied. It has been shown that heat treatment at 500°C leads to an increase in the proportion of micropores, including ultramicropores, in the material. The specific surface area was determined, and the adsorption capacity of the obtained compounds was found to be linearly related to the volume of ultramicropores. A sample with the largest volume of ultramicropores had the highest CO2 adsorption, being 3.12 mmol/g at 273 K and 100 kPa.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
