Abstract
The elastic recovery property of a novel poly(ester-imide-ether) (PEIE) was prepared from the 1, 4-butanediol (BD), poly(tetramethylene glycol) (PTMG1000) and imide dicarboxylic acid based on 1, 2, 4-benzenetricarboxylic (TMA) and aminobenzoic acid (PABA) was studied. The elastic recovery of the PEIE was studied in the fiber form. The influences of the draw ratio, temperature and heat treatment on elastic recovery were investigated. The results show that the novel PEIE possesses the excellent elastic recovery at low temperature and the quickly-changed temperature is lower than that of traditional poly(ester-ether)s. Meanwhile, the heat treatment process can improve the elastic recovery of the PEIE because this process improves the crystallization of the hard segments.
