Xue degraded the rigid polyurethane foams with fatty amine (such as diethylenetriamine,
triethylenetetramine, four ethylidene five amine). The main reaction included the fracture of carbamate
base, urea base, biuret base and urea base formic acid ester base, and the generation of polyol, multiple
amine and aromatic compounds in the degradation process
