| Abstract: | In this study,three kinds of double-amino end-capping(poly)imide acids with different molecular weights were synthesized.These(poly)amide acids were used with Moca as chain extender to prepare the PU elastomers.This series of elastomer were characterized.Properties and micro-phase separation were investigated.The results showed that the PU with(poly)imide acids as extender had a clear structure of micro-phase separation and good thermal stability and mechanical properties. |
