| Abstract: | PP/PP-g-MAH/OMMT nanocomposite was obtained via melt intercalation with organic montmorillonite(OMMT),using PP-g-MAH as coupling agent.The processing properties and rheology behavior of the composites was studied.The results show that with the increase of OMMT,the MFR of PP/OMMT and PP/PP-g-MAH/OMMT nanocomposites falls.With the increase of shear rate,the E_a of PP/OMMT nanocom-posites descends lower than that of pure PP,PP/PP-g-MAH/OMMT nanocomposites with higher content OMMT has higher E_a.Whenωis the same,the G’,G" of PP/OMMT nanocomposite are higher than those of pure PP,the tanδof PP/OMMT nanocomposite is lower than that of pure PP.The PP/PP-g-MAH/OMMT with higher OMMT content shows higher E_a,G’,G" and lower tanδ. |
