Abstract

A study is conducted to describe a one-step synthetic approach using NMP to prepare network polymers with dynamic alkoxyamine crosslinks that allows for reprocessing in the melt state through repeated bond formation and dissociation. With this method, we use stable nitroxide radicals containing a polymerizing moiety as both radical regulators during reaction and branch units on the polymers or crosslinker chains. The study also uses bifunctional initiators to generate chains with radical sites on both sides to connect the nitroxide branch units, resulting in crosslinked polymer.
