Front Cover: In article number 2000053 by Rumiana Dimova, Bernhard V. K. J. Schmidt, and co‐workers, the double hydrophilic block copolymer poly(N,N‐dimethylacrylamide)‐b‐pullulan shows a unique aggregation behavior in aqueous solution at concentrations above 20 wt% leading to a polymer rich and a polymer depleted phase. At this concentration crosslinking is performed to synthesize hydrophilic particles in the size range of 30 nm to 1 µm that are stable at low concentration and in organic solvent.

聚（N，N-二甲基丙烯酰胺）-b-支链淀粉双亲水嵌段共聚物的聚集和交联

前封面：Rumiana Dimova，Bernhard VKJ Schmidt和同事的文章编号2000053中，双亲水嵌段共聚物聚（N，N-二甲基丙烯酰胺）-b-普洛兰在20 wt％以上的水溶液中表现出独特的聚集行为％导致聚合物富相和聚合物耗尽相。在该浓度下，进行交联以合成在30nm至1μm的尺寸范围内的亲水性颗粒，其在低浓度下和在有机溶剂中是稳定的。
