一种新型含萘聚醚酰亚胺的合成与表征

A novel dichioro-monomer 4, 4′-bis(N-′phenyl-4-chloro-1,8-naphthalimide) ether(BCNPI) was successfully prepared. We obtain novel polyethernaphthalimide(PENI) from BCNPI and Bisphenol A salt in the present of sulfolane. The polymer possess high molecular weight from test of intrinsic viscosity and high T_g from the differential scanning calorimetry. The polyetherimide exhibited excellent thermal and thermooxidative stabilities, and it has high modulus, strength and elongation from the test of the mechanical properties.
