We designed twelve types of weak polyelectrolytes (i.e., PEO-b-PMMA copolymers (BCP) in multi-arm structures, where six include EO blocks as joint points and the other six have MMA blocks as joint points). Of these, six are displayed; structures with EO blocks as joint points on the left, and those with MMA blocks as joint points on the right.
Reverse architecture of BOnEOmBOn block copolymers enables the formation of micellar clusters and viscous gels at low concentrations by chain bridging.
