摘要
One novel difunctionalized polyhedral oligomeric silsesquioxanes （POSS） derivative was designed and synthesized by a convenient method with high yield. 1H NMR and P＇r-IR characterizations suggested that Michael addition reaction successfully took place between 2-hydroxyethyl acrylate （HEA） and aminopropylisobutyl POSS （POSS-NH2） 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.
