METHOD FOR TREATING POLYESTER RESIN

PROBLEM TO BE SOLVED: To provide a method for treating a polyester resin which can effectively reduce the amount of oligomers such as a cyclic trimer and, simultaneously, can render the residual amount of the entrainer in the resin small. SOLUTION: In the method for treating a polyester by subjectin...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for treating a polyester resin which can effectively reduce the amount of oligomers such as a cyclic trimer and, simultaneously, can render the residual amount of the entrainer in the resin small. SOLUTION: In the method for treating a polyester by subjecting the polyester resin to contact treatment with a mixed fluid of a supercritical fluid and an entrainer, a poor solvent for polyester oilgomers is used as the entrainer.
