One novel difunctionalized polyhedral oligomeric silsesquioxanes(POSS) derivative was designed and synthesized by a convenient method with high yield.~1H NMR and FT-IR characterizations suggested that Michael addition reaction successfully took place between 2-hydroxyethyl acrylate(HEA) and aminopropylisobutyl POSS(POSS-NH_2) under mild conditions,which finally formed bi(hydroxyethyl) ester-functionalized POSS derivatives(BH-POSS).Due to the similar functional groups and high reactivity,BH-POSS could be easily incorporated into the main-chain of biodegradable aliphatic-aromatic copolyesters PBTL via in situ melt polycondensation to prepare corresponding degradable nanohybrids with high mechanical properties.
