Abstract：Considerable efforts of modification research have been made to convert bio-based materials into thermoplastic materials since the latter half of 20th century, while a new concept of the plasticity-processing of bio-based materials was suggested by the scientists in the recent years, and the related investigations have been performed. In this paper, on the basis of brief introduction of the modification research on the thermoplasticization of bio-based materials and in view of the relationship between the viscoelasticity and its structure-properties of the main components of bio-based materials, the basic principle of plasticity-processing of bio-based materials was discussed. The possible technical route for the plasticity-processing of bio-based materials was further put forward by means such as the dynamic plasticization of bio-based materials and the subsequent bio-based material-plastic compounding. This may open a different way of the processing of bio-based material resources for its effective utilization.
