Abstract: The international community has attached great importance to nitrosoamines, a carcinogen, produced from production of synthetic rubber. This carcinogenic problem has become a technological barrier to internationalization of rubber products. Therefore, PetroChina Jilin Petrochemical Company began a technological research project on environmental-friendly styrene butadiene rubber - SBR1502E. A new-type environmental-friendly terminator suitable for the production process of emulsion polymerized styrene butadiene rubber is selected on the basis of the research. Industrialization test of environmental-friendly styrene butadiene rubber SBR1502E has been successfully completed at the company’s styrene butadiene rubber facility, establishing the industrialized production technology. The main creative achievements include the environmental-friendly two-component compound terminator with an appropriate vapor-liquid ratio and gas-phase and liquid-phase dual polymerization resistant effect. The two-point feeding process of termination agent is adopted for the first time, bringing about independent adjustment of two-component feeding for termination agent. The production technology is an industrial leader at home.
