Reactive Aromatic Hyperbranched Polyester on the Properties of Unsaturated Polyester |
| 초록 |
The purpose of this study was to improve the toughness of UPE resin using aromatic hyperbranched polyester. The aromatic hyperbranched polyester(HBP) was synthesized and the end-group of the polymer was modified to methacrylate-terminated hyperbranched polyester.(MA-HBP) HBP and the synthesized MA-HBP were characterized using 1H-NMR and DSC. MA-HBP was blended with UPE up to 5 phr. The glass transition temperature was not affected by addition of MA-HBP, but the thermal stabilities of UPE blend with MA-HBP increased. It was found that the fracture toughness of UPE blended with MA-HBP increases 25%, as MA-HBP was added up to 3 phr. It shows slight decrease with further addition of MA-HBP to 5 phr. |
