Abstract
The dynamic properties of SBR1502/SBR1712/BR9000 blends are investigated.The results show the confluent property of three polymers is better.The molecular flexility and wet hold of SBR1502 and SBR1712 is elementally same,but the heat generation property of them is different.The tanδ value and location can be adjusted by controlling the level of the blends to obtain a tread rubber with different wet hold and rolling resistance.
