It has good elasticity, wear resistance and low temperature resistant performance is good, low heat, small hysteresis loss, flexing resistance, crack resistance, and the advantages of good dynamic performance, can and natural rubber, neoprene, nitrile rubber, etc. And, in the tire, impact modified, tape, rubber hose and rubber shoes and other rubber products are widely used in production. This design from the basic properties of the butadiene rubber, the present status and development prospects of the polymerization section to the processing section for material balance, obtained the material balance figure。 polymerization process of heat balance, lay a foundation for equipment calculation。 of polymerization process of all kinds of equipment selection, equipment position, production method, production system for the determination of reasonable, the reasonable process parameters and operating procedures. According to determine the technological process and control scheme， draw the control points of process flow diagram， the polymerization kettle assembly drawing and workshop layout； piled the 2 x 107 kg/year cisbutadiene rubber production workshop process design manual. After the final accounting， 2 x 107 kg/year cisbutadiene rubber production workshop process design ply with the design requirements， all parameters are standard.
