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…

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…

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…
