| Abstract: | The effect of vibration on rheological behavior of polyolefins was studied through the selfmade vibration extrusion equipment.The results show that: the apparent viscosity of HDPE and PP reduces under the vibration field,the relationship between vibration field and the apparent viscosity is associated with vibration frequency,die temperature and screw rotational speed. |
