Determination of the Thermal Decomposition Kinetics of Polyurethane Foam by Guggenheim's Method

Abstract

The kinetics of the thermal degradation of a rigid polyurethane foam used to reduce gun wear was determined to illustrate how Guggenheim's method could be applied to polymer decomposition. The polyurethane foam decomposed in two distinct steps. The first order activation parameters for each rate coefficient are k sub 1 = 2.0x10 to the 10th s -1EXP(-134kJ/mole/RT) and k sub 2 = 1.2x10 to the 10th s -1EXP(-154kJ/mole/RT).
