摘要：

In this work, the properties of chitosan (CTS) and synthetic polymers are combined to produce a novel hybrid synthetic natural material. Poly(methyl methacrylate) (PMMA) and glycidyl methacrylate (GMA) are reacted with CTS to produce a versatile material for dental filler applications. This process involves the synthesis of CTS-g-GMA that is further reacted with PMMA [(CTS-g-GMA)-g-PMMA]. The chemical structure and physical properties of the resulting materials is analyzed by FTIR, DSC, SEM, NMR and XRD. The results revealed the evidence of strong intermolecular interactions between CTS-g-GMA and PMMA by covalent bonding formation. Thermal stability of the final copolymer [(CTS-g-GMA)-g-PMMA] is higher than its precursor, CTS-g-GMA. Presented results show a simple route to produce natural-synthetic polymers for potentially useful applications. (C) 2007 Elsevier Ltd. All rights reserved.
