摘要

<正> Flexible oxyethylene-ether was introduced into the aromatic copolyesters and copoly（es-ter-amide）s to reduce the melting point of resulting polymers. The melting point was greatlyreduced to 200℃ or even lower in some cases

and the molecular weight was satisfactorilyhigh as reflected by inherent viscosity. The polymers exhibited high thermal stability and goodmechanical properties as determined by TGA and mechanical tests. The copolyester showedbetter crystallinity and liquid crystallinity than corresponding copoly（ester-amide）s with simi-lar monomer composition as reflected by POM observation and WAXD study. The meltingpoints for both copolyesters and copoly （ester-amide）s showed great dependence on the p-acetoxybenzoic acid （PAB） content in monomer composition and reached the lowest valuewhen PAB was 29 mol%.
