Method for preparing styrene-butadiene rubber having low combined styrene content
The present invention relates to a method for preparing a low styrene-butadiene rubber having a low combined styrene content and, more particular, to a method for preparing a low styrene-butadiene rubber, wherein the low styrene-butadiene rubber contributes to an excellent polymerization rate and vulcanization rate by using an aliphatic organic acid and a sulfonate based compound as emulsifiers, and is excellent in heat stability after blending, thereby improving the workability and viscosity in in roll processing, such that the low styrene-butadiene rubber is advantageous to produce a molded article with improved rigidity and hardness when mixed with a high styrene-butadiene rubber.
