摘要：
The thermal stability of the blends based on polylactide and low-density polyethylene of various compositions is studied. A decrease in the degradation temperature is observed with an increase in the polylactide content in samples (from 414 degrees C for 100% polyethylene to 364 degrees C for 100% polylactide). The influence of aged polyethylene on the thermooxidative degradation of the blends containing 30 wt % polylactide is studied. The third component (aged polyethylene) is determined to accelerate the initial oxidation stage.
