Living Radical Polymerization 4. Stereospecific Living Radical Polymerization
International Polymer Science and Technology, 2010 Living radical polymerization (LRP) enables the control of molecular weight and molecular weight distribution of polymers synthesized, but it is no effect on stereoregulation (tacticity) of the polymer. With the progress of stereospecific radical polymerizations, several attempts have been made to combine it with LRP to achieve simultaneous control of ...

Living Supramolecular Polymerization of DNA
Macromolecular Rapid Communications, 2018 AbstractRecently there have been notable synthetic successes in supramolecular polymerization. By contrast, it has long been known that DNA can undergo supramolecular polymerization (concatemerization). Concatemerization is a step‐like polymerization and consequently suffers from broad molecular weight distributions and generally undesirable ...
