CO2-releasing blowing agents from modified polyethylenimines slightly consume isocyanate groups while foaming polyurethanes

Carbon dioxide adducts from polypropylene glycol (PPG)-grafted polyethylenimines (PEIs) are promising alternatives to the traditional, climate-changing blowing agents for polyurethanes (PUs). Their commercialization is hindered by the fact that they can restore their original polyamine structure whe...
