Method for preparing styrene-butadiene rubber and styrene-butadiene rubber
The present invention relates to a method for preparing styrene-butadiene rubber in which a molecular weight modifier containing two or more components is used in a polymerization reaction and each of the two or more components is added at a optimal time, and the method is capable of improving physical properties of the prepared styrene-butadiene rubber, and styrene-butadiene rubber prepared thereby. The styrene-butadiene rubber prepared according to the preparation method of the present invention has improvement in characteristics such as tensile strength, elongation, etc., and thus may be usefully used in the production of a tire having environmental friendliness, abrasion resistance, and the like.
