Polyimides films were prepared from 3,3',4,4'-BPDA and three different diamines,4,4'-ODA,4,4'-DABP and DPEB with PA as end-capping.They were characterized by DMTA,TGA and mechanical analysis.The results show that the glass transition temperature of polyimides and the tensile strength of the films were improved when the phenylethynyl was a pendent group.When the content of the diamine DPEB increased,the glass transition temperature of cured polyimides DPEB/4,4'-ODA/3,3',4,4'-BPDA/PA increased from 315.3℃ to 354.0℃.The tensile strength of PPEIs also increased from 76.5 to 164.0 MPa.The weight loss temperature(T_5%) of PIs was in a range of 491.9~499.8℃.The glass transition temperature of cured polyimides DPEB/4,4'-DABP/3,3',4,4'-BPDA/PA increased from 350.5℃ to 379.2℃.The tensile strength of PPEIs also increased from 106.5 to 129.8 MPa.The weight loss temperature(T_5%) of PIs was in a range of 483.9~493.0℃.
