摘要： A process for producing a thermoplastic elastomer composition which comprises dynamically cross-linking an olefine copolymer rubber and an olefine plastic using a twin-screw extruder, said process being characterized in that said twin-screw extruder comprises one or more kneading zones within a dynamically cross-linking area and the first kneading zone among said zones comprises a screw with forward kneading disks having a minimum thickness (T min ) of less than 13 mm per disk. Said method enables production of a thermoplastic elastomer composition of good quality regardless of the scale of production.
