| Abstract: | A series of aliphatic-aromatic polyimides were synthesized.These polyimides were prepared by polycondensation of 1,6-diaminohexane,m-phenyldiamine with biphenyl tetrcarboxylic dianhydride(BPDA) at low temperature.Various ratios of 1,6-diaminohexane to m-phenylenediamine were discussed.The structure of product was characterized by IR.The thermal stabilities were investigated by DSC and TG.The mechanical properties were measured by the omnipotent material of electron experiment machine.The results showed that the thermal stabilities and mechanical properties of product were excellent and the processibility was perfect. |
| Keywords: | low-temperature polycondensation polyimide characterization mechanics performance |
