Synthesis and characterization of UV-curable maleimide-terminated imide oligomers

- A UV-curable polyimide is successfully developed.
- The imide oligomers are capable of polymerizing rapidly with and without reactive diluents under UV-radiation.
- It has been proposed that the NVP could react with imide oligomers via a donor/acceptor complex, and the DMAA could not due to the electron-poor double bond.
