Abstract

PURPOSE: To prepare a copolyester resin useful as fibers, films, bottles, etc., free from gelation when melted, and having excellent dynamic properties, thermal deformation resistance, flame resistance, etc., by incorporating specific imide ring- containing ester unit.
CONSTITUTION: A linear thermoplastic copolyester having a structure consisting of (A) the unit I, (B) the unit II and (C) the unit III, wherein (C)/(A) is 75/25 - 0.1/99.9 (molar ratio). The copolyester is prepared, e.g. by polycondensing terephthalic aicd (derivative) with ethylene glycol (derivative), N-hydroxyethyl trimellitic imide IV (R1 is H, 1-6C alkyl, etc.; R3 is H or 1-3C acyl ), etc..
