Abstract A preparation method of small graininess polybutadiene latex for ABS is mainly characterized by that under the action of initiating agent, emulsifying agent, alkali, chain transfer agent and electrolyte, the butadiene can be emulsion-polymerized to obtain the invented product. By adopting compounded emulsifying agent formed from disporportionated rosin acid soap or potassium oleate and alkyl sulfate or alkane sulfonate, the said invention can utilize one-step batch to prepare small graininess polybutadiene latex with 80-120 nm within 8-11hr.
