The TPS or the TPS/CMC blend was melt-blended with PE-MAH using a two-roll mill at 160 °C for 10 min. The samples were compressed into sheets using a hot-compress machine at 160 °C for 3 min. The final compositions of the blends and their codes are shown in Table 1 .
The two-roll mill technique employed for exfoliating unmodified nanoclay is not adequate. N116 nanoclay shows no influence on the hydrolytic degradation and mechanical properties, decreases crystallinity, and increases the viscosity of TPU-PCL/PCL blend.
