| Abstract: | COPNA resins were synthesed from anthracene and terephthalic aldehyde under the catalysis of p-toluensulfonic acid(PTS). Accoroling to the synthesis experiments, it is found that the optimum reaction temperature is 190℃，and that the optimum mass fraction of PTS is 5%. The analysis of IR and NMR of the resins show that electrophilic substatution occurred between anthracene and terephthalic aldelyde under acid catalysis. The experimental results also show that the thermogravimetry of the COPNA resin with 1.0 mole ratio of TPA to Ant begins obviously at 400℃，the maximum thermogravimetric rate occurred at 529.1℃, the rate is 2.63%/min, and carbonorphism yield is 58.7% at 800℃. The heat-resistance of the COPNA resin was measured. |
