Disclosed herein are starch stabilized polymeric emulsions. Persulfate salts degrade starch to give it suitable characteristics, and then also, essentially simultaneously, initiate polymerisation with monomers. Thi s permits a single reaction condition to be used for both the degradation step and the polymerization step, and avoids the need for use of metallic ions such as iron.
