Front Cover: Reversibly coagulatable and redispersible polyacrylate latexes are prepared by emulsion (co)poly‐merization of methyl methacrylate (MMA) using a polymeric surfactant, PDMAEMA‐block‐PMMA. The resulting PMMA latexes can be readily coagulated with a trace amount of caustic soda. The coagulated latex pastes, after washing, can also be redispersed into fresh water to form stable emulsions by CO2 bubbling with ultrasonication. The coagulation and redispersion processes are repeatable. Further details can be found in the article by Q. Zhang, G. Yu, W.‐J. Wang,* B.‐G. Li, and S. Zhu* on page 916.
