Beschreibung
Zusammenfassung:	The invention relates to a method for obtaining an elastomeric composition by extrusion, said composition being based at least on: - a copolymer A based on at least one ethylene monomer and at least one vinyl acetate monomer; and a reinforcing filler comprising at least one inorganic reinforcing filler, the method delivering, at the extruder output, the extruded composition in which the dispersion of the reinforcing filler has a z-score higher than or equal to 80, and being such that the specific mechanical energy transmitted to the composition during the method is within a range from 1000 J/g to 14 400 J/g. The compositions obtained according to the method are intended for the manufacture of tires or semi-finished products for tires.
