摘要：

1,6-Hexamethylenediamine (HMDA) is utilized to synthesize copolyimides based on bisphenol-A dianhydride and 4,4-oxydianiline or 1,4-bis(4-aminophenoxy) benzene. The purpose of this study is to modify the processability of aromatic polyimides for textile processing and melt property requirements. Polyimides containing an aliphatic HMDA are synthesized via random and block copolymerizations. Variations in the aliphatic content produce a series of polyimides that have different thermal stability, mechanical properties, and processing characteristics. Based on the results, polyimides synthesized with 25 % HMDA have better mechanical properties compared to other contents of HMDA, and block copolyimides have better processability with higher melt index than random copolymers.
