Polyurethanes (PU) are versatile materials displaying desirable properties that can be modified through the addition of fillers. The introduction of organoclay into the matrix can change the mechanical and overall properties of the polymer. In this paper, the effect of clay concentration on the behavior of crosslinked polyurethane was investigated. The prepared systems were evaluated through analytical techniques in which their rheological and dynamic mechanical properties were studied. Results demonstrated that the introduction of clay improved the storage modulus by more than 30%. Furthermore, clay decreased the molecular weight and viscosity of nanocomposite solution by 40% and 90%, respectively for up to 10 wt% clay, which significantly improves processability.
