The strain induced crystallization behaviour in polyimide from 1,4-bis (3', 4'- dicarboxyphenoxy)benzene and 4,4'-oxydianiline (PEI-E)has been investigated by WAXD, DSC and FTIR. The results obtained show that crystallization in PEI-E did take place just after tensile yielding. Meanwhile, the effect of strain induced crystallization on the thermomechanical properties was studied by DMA and TMA, the results of which indicate that the crystallization and hot stretching have a certain influence on the dynamic mechanical properties,such as weakening the β relaxation and decreasing the glass transition temperature.The TMA results confirm the shifting of glass transition temperature to lower temperature region after hot stretching.This phenomenon could be well explained by the effect of residual stress according to Eyring's theory.
