<P>PROBLEM TO BE SOLVED: To produce a composition containing a liquid crystalline polyester and a platy filler, which hardly causes blisters under high temperatures. <P>SOLUTION: The composition is produced by: employing an extruder having a cylinder and a screw disposed inside the cylinder; feeding the liquid crystalline polyester and the platy filler to the cylinder while rotating the screw; and melt-kneading the content to be extruded. In this case, (the length L (mm) of cylinder)/(the inner diameter D (mm)) is 50 or more; the diameter of the screw is 50 mm or less; and (the number R (rpm) of revolutions)/(the amount P (kg/h) extruded from the extruder) is 4 or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
