Abstract: The structure and dynamic properties of the starch xanthate/carbon black/natural rubber composites were analyzed by using scanning electronic microscopy( SEM),rubber process analyzer( RPA) and dynamic mechanical analyzer( DMA). The results showed that the interface bonding force of the composites when loaded with starch xanthates was improved effectively between filler or rubber ingredients and rubber matrix. The DMA results showed that the composites increased slightly their glass transition temperature,wet skid resistance,and rolling resistance and decreased their heat build-up and relaxation activation energy. Under strain,the compounds with different parts of starch xanthates increased slightly their Payne effect and dielectric power factor( tanδ) but had opposite results as frequency decreased,and the G’ of the compound was best when the compound was filled with 6 parts of the starch xanthates.
