✦ Synopsis

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 β€’ C. The evolved gas analysis was performed using a quadrupole mass spectrometer and Fourier transform infrared spectrophotometer equipped with external modulus for gas analyses.

## Abstract The structure of the crystalline hard domains of polyurethane elastomers based on 1,5‐naphthalene diisocyanate (NDI) has been investigated by X‐ray methods. The specimens were pressed films prepared from NDI and 1,4‐butanediol (chain extender), with poly(oxytetramethylene) as the soft s
