Abstract
A process is provided for agglomerating small rubber particles in an aqueous latex to form large rubber particles. The process involves the addition of a water soluble organic acid and a water soluble organic anhydride to the latex prior to agglomeration of the rubber particles to facilitate agglomeration of the rubber particles into large rubber particles which are essentially free of coagulum. The latex of large rubber particles is useful in the preparation of ABS polyblends.
