Synthesis and romp of modular norbornene derivatives for the preparation of polymers with cationic amphiphilic repeating units

摘要

In this study, an amphiphilic monomer structure has been targeted where the amphiphilicity can be tuned at the repeating unit level, giving rise to a polymer backbone structure with regularly spaced hydrophilic and hydrophobic groups. The size of the amphiphilic polymer is aimed to be separately controlled through the choice of the polymerization procedure. Ring-opening metathesis polymerization (ROMP), employing well defined homogeneous catalyst systems, has been a promising technique for the targeted application as it provides flexibility over the choice of functional groups on the monomer unit and a high level of control over the molecular weight and end-groups.
