Abstract

Thermal stability of the blend of polyurethane with three other elastomers, having the reactive functional group, has been studied. Three different blending techniques have been employed to study the effect of processability on the thermal stability of the blend. IR spectral analysis revealed that interchain crosslinking takes place between the two elastomer phases. Thermal stability of the blend increased when preblending and preheating preblending techniques were applied, probably due to the formation of the interchain crosslink between the elastomer phases.
