Abstract: PURPOSE:To shorten reaction time and obtain the subject polyester useful as automotive parts, etc., in a simplified apparatus and operation with high efficiency by continuously carrying out addition polymerization of a crystalline aromatic polyester and lactone compound in a single screw extruder. CONSTITUTION:A crystalline aromatic polyester (e.g. polybutylene terephthalate) and a lactone compound (e.g. epsilon-caprolactone) are fed to a single screw extruder and subjected to continuous addition polymerization to afford the objective polyester. Further, the unreacted lactone compound is preferably removed from the resultant polyester. Furthermore, e.g. 215 to 250 deg.C temperature and 3 to 20min residence time in the extruder are preferably used as conditions of the abovementioned addition polymerization.
