PURPOSE: A multiple-screw extruder in which even conjugated screws will furnish a desirably high level of compositional homogeneity and process stability, is provided. CONSTITUTION: A multiple-screw extruder comprises (a) a first screw about the root of at least one segment of which are disposed flight(s), the number of which flight(s) is x; and (b) a second screw about the root of at least one segment of which are disposed flight(s), the number of which flight(s) is y; wherein the flight(s) on each x-flighted segment of the first screw are intermeshed with the flight(s) on a y-flighted segment of the second screw, and x is not equal to y. |
