Abstract

PURPOSE: To obtain the titled polyester having improved properties of an aromatic polyester and improved easy dyeability, by using a dicarboxylic acid component, a glycol component and further a glycol having a specific structure as a copolymerization component.
CONSTITUTION: (A) A dicarboxylic acid component containing 80mol% or more terephthalic acid (an ester-forming derivative), (B) a glycol component containing 80mol% or more ethylene glycol, tetramethylene glycol and/or 1,4- cyclohexanedimethanol, and (C) a glycol of formuulaI(R is aromatic hydrocarbon; X is alkylidene, sulfonyl, etc.; m and n are integers and 3≤m+n≤12) as a copolymerization component of formula II in an amount of 1W10wt% in the resultant polyester and reacted to give the aimed polyester. Preferably, metallic 5-sulfoisophthalic acid (an ester-forming derivative) is contained in the component (A).
