摘要：
Polyurethane was synthesized using bio-based substances (com. polyol and diisocyanate) and then chem. depolymerized with NH2CH2CH2(NHCH2CH2)(2)NH2 or ethylene glycol using a molar ratio of polyurethane to the decomposing agent of 2:1, 1:1 and 1:2. The chem. structure of polyurethane and the obtained depolymn. products was verified using FTIR. The amine no., rheological properties and thermal stability (using TGA) of the obtained chem. recycling products were detd.
