abstract
The quantitative endcapping of polyethylene glycols with brominesubstituted, dendritic, aromatic polyethers 1 produces amphiphilic block copolymers. In solvents in which both blocks are only slightly soluble or in which only one block is soluble, micelles form. Depending on the solvent, they can alter their size and shape. (Figure Presented.)
