摘要：In this paper, the functional polysilsesquioxane microspheres functionalized by poly(epoxypropoxy)silsesquioxane (PESQ) and poly(epoxypropoxy/amino)silsesquioxane (PEASQ) were grafted onto commercial PLA via functional group reactions through melt processing, and directly used as a novel chain extenders to improve the thermal degradation of PLA. During the whole reaction time 35 min, the torques of P-2PESQ and P-1PEASQ was 60% higher than that of Processed PLA. The addition of PESQ or PEASQ into PLA increased the onset temperature for thermal degradation. ? American Institute of Chemical Engineers.
