Abstract :
Four kinds of thermosetting polyimide materials are prepared from 3,3´-diethyl-4,4´-diamino diphenyl methane (DEDADPM), pyromellitic anhydride(PMDA) and different end capping agents-maleic anhydride (MA), nadic anhydride (NA), methylnadic anhydride (MNA) or methyltetrahydro anhydride (MTHA). Fourier transform infrared spectroscopy (FI-TR) indicated that imide ring has formed. Thermal decomposition temperature (Td) has been tested, the results showed that four materials are different, the decomposition temperature are 470~500degC. Dielectric constant (epsiv) and dielectric loss (tan d) are 2.57-3.15 and 0.008-0.0100, respectively.
