Document Type and Number:
Japanese Patent JP7136166
Kind Code:
B2
Abstract:
To provide a method for producing an aliphatic polyester resin composition capable of satisfactorily dispersing a filler.SOLUTION: A method for producing an aliphatic polyester resin composition kneads an aliphatic polyester resin and a filler at a temperature lower than a melting point of the aliphatic polyester resin in presence of a compressive fluid. The kneading is preferably performed at a temperature lower than a melting point of the aliphatic polyester resin by 20°C or more, and a ratio (aliphatic polyester resin/filler) of a charged amount of the filler to a charged amount of the aliphatic polyester resin is preferably 99/1 to 90/10.SELECTED DRAWING: None
