摘要

improved bonding between the sisal fiber and PP matrix. The relaxation time values calculated at 70℃ for sisal fiber/PP composites with and without MAgPP show that addition of sisal fiber decreases the relaxation time due to shortening of PP chains. Addition of low concentration of coupling agent increased the relaxation lime and further increase of MAgPP concentration decreased the relaxation time value, increase is due to increased bonding between sisal fiber and polypropylene chains. Better bonding between fiber and polypropylene would have created hindrance in the movement of the dipoles, which would have increased the relaxation time.
