Curing of m-APII,a novel acetylene terminated polyisoimide based on asymmetrical biphenyldianhydride (a-BPDA),3,4'-diaminodiphenyl ether (3,4'-ODA) and 3-ethynylaniline endcap was characterized and its composites reinforced with G827 textiles were investigated.From DSC and DMA studies,it is found that m-APII is 250℃ curable with a free standing postcure at elevated temperatures which can give a higher Tg.The G827/m-APII laminates fabricated by compression molding displayed an excellent quality as evidenced by the C-scan and microscopic inspections.The mechanical test results showed that m-APII composites not only had good mechanical properties at room temperature but also exhibited an outstanding retention of properties at 300℃.
