摘要：
A series of star-shaped polylactic acid was synthesized using L-lactic acid (L-LA) and octa(gamma-chloroammoniumpropyl) octasilsesquioxane (POSS-NH3Cl) by in the presence of stannous(II) octanoate (Sn(Otc)(2)) catalyst. The structures and properties of these dendritic polymers were characterized by FTIR, H-1-NMR and TGA, respectively. These results demonstrated that the chemical reaction between POSS-NH3Cl and L-LA had been taken place, and the novel star-shaped polylactic acid (POSS-g-PLLA) had been synthesized. And thermal properties, such as melting temperature and decomposition temperature, were obviously improved along with the increment of the added amount of POSS-NH3Cl. The decomposition temperature of POSS-g-PLLA was higher ca. 70 degrees C higher than that of PLLA, also higher 65 degrees C than that of POSS-NH3Cl/PLLA.
