In this article, degradable polyethylene (PE)-based copolymers containing ester units in the backbone were prepared through the hybrid copolymerization of ethylene and cyclic ketene acetals (CKAs) mediated by dithiocarbamate successfully.

We report the first amine-bearing cyclic ketene acetals (CKAs) for radical ring-opening polymerisation (RROP). The resulting polyesters and their corresponding nanoparticles were biodegradable and showed the desired pH sensitive behaviour.

Radical Ring-Opening polymerization (rROP) of Cyclic Ketene Acetals (CKAs) combines the advantages of both ring-opening and radical polymerization thereby allowing the robust production of polyesters. In this article we investigate in detail the radical ring-opening polymerization of model CKA monomers and demonstrate by the combination of DFT calculations and kinetic modeling using PREDICI software that we are now able to predict <i>in silico</i> the ring-opening ability of CKA monomers<br>
