cyclohexanetetracarboxylic dianhydride, 4,4'-(hexafluoroisopropylidene)diphthalic anhydride. These successful syntheses all result in yields over 70%. Three of the monomers are incapable of forming stable liquids similar to the pyromellitic bisimide. Therefore, we chose the remaining five, namely diallyl ester, diallyl ether, diallyl cyclohexane, diallyl diether, and diallyl hexafluoro [structures shown in Figure legend], which possessed T m 's lower than 160 °C (Figure ). We focus the rest of the study on these remaining five monomers. We chose TMPMP as the thiol monomer to allow direct comparison of each diallyl bisimide monomer with sufficient crosslinking. In the following, we name the poly(imide ester) thiol-ene networks from the five diallyl bisimide monomers as PI-ester, PI-ether, PI-cyclohexane, PIdiether, and PI-hexafluoro.
