The purpose of this work is to analyze the thermal degradation behavior of PHB and its nanocomposites.It was obtained that the isothermal degradation of PHB/MMTs nanocomposites depended on the MMTs modifier and temperature. The thermal stability of PHB and its nanocomposites was decreased with the addition of 4% of clay. According to the type of organomodifiers in the clay, the degradation mechanism changed
