The thermal degradation of a polyurethane elastomer based on 4,4`-diphenylmethane diisocyanate, poly(ethyleneadipate) diol copolyester and extended with 1,4-butanediol has been studied by simultaneous thermogravimetry and differential scanning calorimetry analysis, in nitrogen atmosphere, up to 600 degrees C. The evolved gas analysis was performed using a quadrupole mass spectrometer and Fourier transform infrared spectrophotometer equipped with external modulus for gas analyses. (c) 2010 Elsevier B.V.
