Styrene Butadiene Rubber via an Emulsion Process

Styrene Butadiene Rubber is an elastomer that was originally developed prior to World War II as a replacement for natural rubber. SBR is used for manufacturing vehicle tires, but is also used in other applications, such as: adhesives, flow modifiers for other elastomers, footwear, pharmaceutical and food-contact articles, and even chewing gums.

Technology Description

The following paragraphs describe a cold emulsion-polymerization process for SBR production from butadiene and styrene. SBR grades generated in this type of process are usually referred to as emulsion SBR (eSBR).


Styrene and butadiene are mixed with an emulsifier and demineralized water to form the emulsion that will be fed to the polymerization reactors. The polymerization occurs in a connected series of continuously stirred, jacketed tank reactors. To maintain a low reaction temperature, all reactors are cooled using ammonia refrigeration.

Downstream, a “shortstop” agent is mixed with the emulsion to stop the reaction at the desired conversion stage and avoid gel formation. The shortstopped latex is transferred to the monomer-recovery section.

Monomer Recovery

The latex generated in the polymerization reactors is ...

Coagulation, Drying and Finishing

In the coagulation step, the latex coagulates and becomes ...
