| Abstract: | In this paper, polyurethane fiber wastes was degraded in a bi-screw-Micro Compounder using diethylene glycol as degradation agent. The glycolysis kinetics of the wastes was described by measuring the intrinsic viscosity of the recyclates. A second-order kinetic model of the degradation was proposed based on the experiment results. The rate constants and the activation energy of glycolysis were determined. |
