Published in 2017 at "Asian Journal of Organic Chemistry"

DOI: 10.1002/ajoc.201700152

Abstract: A series of CO2 adducts of α-carbon alkylated N-heterocyclic olefins (ANHOs–CO2) were synthesized and characterized by single-crystal X-ray diffraction analysis. The in situ FTIR studies demonstrated that ANHOs–CO2 adducts showed higher thermal stability than the… read more here.

Published in 2021 at "Journal of Cellular Plastics"

DOI: 10.1177/0021955x20987153

Abstract: CO2 adducts from hydrophobically-modified polyethylenimines (PEIs) in powder form are newly-developed environment-friendly blowing agents for polyurethanes (PUs). However, they are difficult to disperse into foaming systems that usually contain polyether polyols as the PU soft… read more here.

Published in 2023 at "Journal of Cellular Plastics"

DOI: 10.1177/0021955x231177805

Abstract: Recently developed CO2 adducts of alkylated polyethylenimines (PEIs) can replace traditional, ozone-depleting, and/or global warming halogen-containing blowing agents of polyurethanes (PUs). Meanwhile, water is the most common chemical blowing agent that is cheap and also… read more here.
