Abstract
The thermomechanical properties of reclaimed PU samples, containing va rious amounts of degraded waste products of these polymers, were studi ed. As the degraded PU content increases, the network density and the thermal stability of the elastomer decrease, while the rubberlike defo rmability and the melt viscosity increase. Despite certain narrowing o f the working temperature range of the reclaimed polymers, their mecha nical properties are retained even for a 15-% filling with degraded ma terials.
