Co-assembly of precision polyurethane ionomers reveals role of and interplay between individual components.

ABSTRACT: Industrial and household products, such as paints, inks and cosmetics usually consist of mixtures of macromolecules that are disperse in composition, in size and in monomer sequence. Identifying structure-function relationships for these systems is complicated, as particular macromolecular components cannot be investigated individually. For this study, we have addressed this issue, and have synthesized a series of five sequence-defined polyurethanes (PUs): one neutral-hydrophobic, one single-charged hydrophilic, one single-charged hydrophobic and two double-charged amphiphilic PUs (one symmetric and one asymmetric). These novel precision PUs - that were prepared by using stepwise coupling-deprotection synthetic protocols - have a defined composition, size and monomer sequence, where the ch
