Rubber products such as tires

seal ring and conveyer belt

are complex composite material systems composed of rubber materials and a large number of fillers. The chain structure of rubber has a great influence on the properties of the products. Functionalized rubber can give rubber composites higher polymer-filler interaction

lower hysteresis

excellent filler dispersion

lower rolling resistance

excellent wear and fatigue resistance. In this paper

the functionalization methods

chain structure and properties of several general purpose synthetic rubbers

such as SSBR

IR and BR

were reviewed. The high performance direction and application prospect of general purpose rubbers were discussed.
