In the current work, Polyurethane (PU) squander was depolymerized by impartial hydrolytic process in presence of zinc acetic acid derivation and lead acetic acid derivation as impetuses. Degree of depolymerization of polyurathene was concentrated by estimating the amine worth of the item. The best amount of impetuses, including zinc acetic acid derivation and lead acetic acid derivation, was found to be 1g. For the depolymerization of PU froth response, zinc acetic acid derivation was a more strong impetus than lead acetic acid derivation. In light of the amine worth and lingering weight of the depolymerized item, the speed consistent was gotten and viewed as arranged by 10-3 min-1; and the response was viewed as first request. The energy of initiation and not entirely settled by Arrhenius plot were 36.86 kJ mole - 1 and 1.349 x 102 min-1 individually. The enthalpy of initiation at 1500C, 1800C, 2000C, and 2400C was recorded as 43.89, 44.39, 44.72 and 45.37 kJmole-1 individually. The entropy of initiation at the particular temperatures was recorded as 10.37 x 10-2, 9.79 x 10-2, 9.45 x 10-2 and 8.84 x 10-2 kJ mole-1.
