The article reports preparation and characterization of CO2 adsorbents based on hyperbranched polyamines and polyglycerols. Hyperbranched polyglycerol containing primary amine groups (A-HBPG) and polyethyleneimine (PEI) showed to be effective in CO2 capture from the ambient air. Adsorbents based on those polymers were stable for at least 17 adsorption/desorption cycles provided the desorption was performed in oxygen free atmosphere. Amine containing hyperbranched polymers are promising materials for CO2 capture.
