Abstract

A novel methyl tetrahydrophthalic anhydride end-capped imide compound (MODA) was firstly used to promote the curing reaction of phthalonitrile monomer 1,3-bis(3,4-dicyanophenoxy) (3BOCN). The curing behaviors of 3BOCN/MODA blend were studied by differential scanning calorimetry (DSC) and rheological analysis, which suggested that the blend possessed a wide processing window. IR spectra exhibited no triazine has been formed in the curing process and the nitrile group absorption peak almost disappeared after post-cured, the thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA) revealed that the cured phthalonitrile resins have excellent thermal properties and high glass transition temperature (Tg).
