The invention discloses a method and device for synergistically preparing an ultrahigh-viscosity polymer blend. According to the method, a material flows in circularly compressed and expanding modes during periodical change of the size, and is under the size tensile stress effect in the direction consistent with the flowing direction, ultrasonic vibration is superposed in the direction perpendicular to the flowing direction through an ultrasonic device arranged at a through hole of an eccentric stator, and polymer material mixing under the synergistic effect of the vibration shear stress and the size tensile stress is achieved. A rectangular through groove is radially formed in a rotor shaft of the device, a sliding plate is placed in the radial rectangular through groove of the rotor shaft, a volume enclosure space is divided into two periodical change parts by the sliding plate, and the two parts communicate through a passing groove; a vibration transmission rod is connected with an ultrasonic generator; and the vibration transmission rod is mounted in the through hole of the eccentric stator through a flange plate and a flange. The processes of mass transfer and heat transfer in the mixing process are reinforced, and the characteristics that a mixing device is simple in structure, high in mixing efficiency, good in mixing property and capable of being automatically cleaned are achieved.
