摘要：

The effects of K2S2O8, palm fiber length and maleic anhydride (MA) on the physical properties of the green composite made of low grade natural rubber (LNR), cassava starch (CSt) and palm fiber prepared by using two-roll mill and compression molding were investigated. The tensile strength of LNR/CSt composite containing 10% palm fiber with < 450 mu m fiber length was improved by addition of 1 g K2S2O8. The swelling ratio in toluene of this composite was dramatically decreased due to the higher interaction between polymer matrix and fiber confirmed by SEM images. The highest tensile strength and the lowest swelling ratio in toluene was obtained with using 0.5 K2S2O8, 0.2 MA and palm fiber length of < 450 mu m.
