Polyurethane Recycling: Thermal Decomposition of 1,3-Diphenyl Urea to Isocyanates
Substituted urea linkages are formed during the production of polyurethane foam. To chemically recycle polyurethane toward its key monomers via depolymerization (i.e., isocyanate), it is essential to break the urea linkages to form the corresponding monomers, namely, an isocyanate and an amine. This...
