| Abstract: | Two Gd-containing urushiol-based polymers, including urushiol-Gd polymer (PUG) and urushiol-aniline-Gd polymer (PUAG), were obtained by the reaction of GdCl3 and urushiol or urushiol- aniline-formaldehyde condensation polymer. Indicated by the characterization of IR, XPS, dynamic mechanical thermo-analyzer (DMTA) and DSC-TG, there are the coordination between Gd(III) and oxygen atom phenolic of hydroxyl group within the polymers. Moreover, the further crosslinking reaction take place within the side chain of the urushiol-based polymers and result in the higher modulus and improved thermal stability of the polymers. The heat resistant of PUAG is better than PUG. |
