摘要： The present invention relates to a method of acrylonitrile-butadiene-styrene (ABS) rubber latex, and the acrylonitrile-butadiene-styrene (ABS) latex is prepared by graft-polymerizing butadiene rubber with the monomers of acrlylonitrile and styrene through emulsion-polymerization, so that the ABS rubber latex of the present invention has high solid content. The method of ABS rubber latex of the present invention comprises the step of emulsion-polymerizing i) polybutadiene rubber latex; ii) aromatic vinyl compound; and iii) vinyl cyanide with the addition of a reactive emulsifier. According to the method of the present invention, the ABS rubber latex has high solid content due to a decrease in the amount of coagulated materials and film, which formed on the rubber latex during polymerization, and an increase in the production volume.
