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. This 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.
L'invention concerne des émulsions polymères stabilisées par l'amidon. Des sels de persulfate dégradent l'amidon pour donner à celui-ci des caractéristiques adéquates, et commencent presque simultanément la polymérisation à l'aide de monomères. Ce processus permet d'utiliser une condition de réaction unique à la fois pour l'étape de dégradation et celle de polymérisation, évitant ainsi l'emploi d'ions métalliques tels que le fer.
