Imide groups were introduced in the hard segment of UV cured polyurethane dispersion (UV-PUD) by extending the NCO terminated prepolymers with pyromellitic dianhydride (PMDA) where the soft segments were prepared from PTMG, H12MDI, HDI and DMBA. It was found that imide hard segment, as compared with conventional urethane hard segment gave remarkably high mechanical properties as well as thermal stability in terms of decomposition temperature and dynamic mechanical properties at elevated temperatures, and the results were interpreted based on the partial mixing of soft segments and imide hard segments.
