Method for producing aliphatic polyester |
| abstract |
The present invention provides a method for producing an aliphatic polyester resin capable of efficiently reducing the cyclic dimer contained in the aliphatic polyester resin. An aliphatic polyester resin after a melt polycondensation reaction is melt-extruded and devolatilized using a twin screw extruder under a condition that the resin temperature at the outlet of the twin screw extruder is 220 ° C. or higher and 270 ° C. or lower.
