We reveal faster urethane and slower urea cleavage kinetics in polyurethane foam, indicating acid effects influence depolymerization rates.
Polyurethane foam contains urethane and urea bonds, yet their depolymerization kinetics have not been separated until now. We reveal a fast urethane and a slower urea cleavage, with the latter strongly influenced by acid elctronic effects.
