| Abstract: | Take environment-friendly styrene-butadiene rubber SBR1502E of Jilin Petrochemical Company as the research object. The effects of pH value of the coagulating liquid on the properties of SBR gums were investigated. The result showed that：without changing the coagulating liquid tempera-ture,latex feeding quantity and polymer flocculant adding amount, the pH value of the coagulating liq-uid has a great influence on the mechanical properties of SBR gums. When the initial pH value is be-tween 3.0 and 3. 5, the properties of environment-friendly styrene-butadiene rubber SBR1502E can meet the technical standards for excellent level product. |
