| 英文摘要 | A series of new polyimide oligomers and resins terminated with 4-phenylethynylaniline were synthesized using 4, 4'-oxydiphthalic anhydride ( ODPA), 3, 3', 4, 4'-biphenyltetracarboxylic dianhydride ( s-BPDA), 3, 4'-oxydianiline (3, 4'-ODA), and 1, 4-bis (4-amino-2-trifluoromethylphenoxy) benzene ( BTPB). The phenylethynyl terminated polyimide oligomers and resins were evaluated by their chemical structure, thermal properties and rheological properties. Experimental results showed that all these oligomers were crystal line. The PETI oligomers based on ODPA dianhydride exhibited lower melt viscosity and low-viscosity temperature range, which made PETI oligomers have more wide process window. After cured at 371 degrees C for 1 h, all PETI resins showed good thermal stability, and PETI resins based on BPDA have high glass transition temperatures. The diamine composition of BTPB and 3, 4'-ODA has effect on both melt viscosity and thermal stability of oligomers and resins, especially on the melt viscosity of PETI oligomers based on BPDA. In addition, the thermal cure reaction of 4-phenylethynylaniline., terminated oligomers occurred obviously at about 300 degrees C. |
