| Abstract: | The emulsion polymerized styrene butadiene rubber SBR （ESBR） was modified by purification, and the processing and physical properties of the modified ESBR （TSBR）, ESBR and solution styrene butadiene rubber （SSBR） were compared. The application of those three types of SBR in the tread compound by blending with natural rubber （NR） and polybutadiene rubber （BR） was then investigated. The results showed that the carbon black dispersion, curing characteristics and physical properties of TSBR were better than those of ESBR, and the heat build-up was lower. The elasticity of TSBR vulcanizates was better than SSBR. TSBR could be used in high- performance tire tread. |
