Abstract
The present invention relates to a method for preparing a styrene-butadiene latex, more particularly to a method for preparing a styrene-butadiene latex comprising the steps of adding a transition boosting agent to a styrene-butadiene copolymer, stirring the mixture and deodorizing the product. Since unreacted residual monomers and volatile organic compounds are reduced significantly, foul smell during drying at high temperature, irritation to skin and eyes and foul smell of the final product can be prevented.
