Abstract

Monodisperse hyper‐crosslinked polystyrene nanospheres with ultrahigh specific surface area were successfully prepared by emulsifier‐free miniemulsion polymerization and post‐crosslinking. The specific surface area and the total pore volume of hyper‐crosslinked nanospheres were increased with increasing the concentration of vinybenzyl chloride in monomer mixture. The hyper‐crosslinked nanospheres exhibited excellent swelling capacity in thermodynamically good and poor solvent. Furthermore, the nanospheres with specific surface area of 1 223 m^2^ · g^−1^ adsorbed 2.13 wt.‐% hydrogen at 163 K/1.5 MPa. Overall, the present study provided a simple method to prepare monodisperse microporous hyper‐crosslinked polymer nanospheres.
