Abstract
The present invention provides a method for producing a liquid-crystalline polyester resin composition, the method comprising providing a twin-screw extrusion granulator that comprises a cylinder provided with at least one supply port and two screws installed in the cylinder; supplying (A) a liquid-crystalline polyester and (B) a titanium oxide filler into the cylinder through one of the at least one supply port; and melt-kneading the components (A) and (B), wherein a cylinder setting temperature is set at a temperature of (Tm−10)° C. or lower wherein Tm is a fluidization temperature of the component (A).
Claims7
A method for producing a liquid-crystalline polyester resin composition, the method comprising:
- providing a twin-screw extrusion granulator that comprises a cylinder provided with at least one supply port and two screws installed in the cylinder, and a heater for heating the cylinder;
- supplying
- (A) a liquid-crystalline polyester and
- (B) a titanium oxide filler into the cylinder through one of the at least one supply port;
- and
- melt-kneading the components (A) and (B),
- wherein the heater heats the cylinder to a temperature of (Tm−10)° C. or lower wherein Tm is a fluidization temperature of the component (A).
