To meet the R/D needs of polymer industry and industrialization of new polymer materials, an elongation rheologybased polymer deformation processing method for polymer material processing and molding is presented, which realizes the transformation of the principle and method of polymer material processing and molding from ‘shear deformation’ to ‘elongational deformation’. The structural principle and technical characteristics of the eccentric rotor plasticized transport device controlled by volume elongational rheology are elaborated, and the application advantages of this technology in self-reinforcement of general material processing and efficient processing of special materials are discussed. It is shown that the eccentric rotor plasticization transportation technology has obvious advantages such as good compatibilizing effect, excellent mixing and dispersion effect, less fiber breakage and fracture in multi-component plastic blending compatibilization modification, organicinorganic hybrid function modification and thermoplastic fiber reinforced modification, etc. as compared to traditional screw plasticization transportation technology. In addition, the volumetric compression and release effect of the eccentric rotor plasticizing and transporting device can strengthen the mass and heat transfer effect of melting and plasticizing process, greatly shorten the material thermomechanical process, and realize high-speed molding processing of extreme rheological behavior material.
