Abstract: Radical Ring-opening polymerisation (RROP) of cyclic ketene acetals (CKAs) emerges to be a valuable polymerisation technique. In attracting more attention, RROP has seen a new spike in publications, which we will put into perspective. This… read more here.

DOI: 10.1021/acs.biomac.2c00851

Abstract: A small library of degradable polyester-like glycopolymers was successfully prepared by the combination of radical ring-opening copolymerization of 2-methylene-1,3-dioxepane as a cyclic ketene acetal (CKA) with vinyl ether (VE) derivatives and a Pd-catalyzed thioglycoconjugation. The… read more here.

DOI: 10.1021/acs.macromol.6b02778

Abstract: By condensing 1,1-dicarboxy-2-vinylcyclopropane with l-alanine methyl ester, a new chiral vinylcyclopropane derivative bearing two amide moieties 1 was synthesized. The vinylcyclopropane thus prepared was separated into two epimers, namely, RSS-1 and SSS-1. Both the epimers… read more here.

DOI: 10.1021/acsmacrolett.2c00298

Abstract: Macromolecular cryoprotectants based on polyampholytes are showing promise as supplemental cryoprotectants alongside conventional DMSO-based freezing. Here we exploit radical ring-opening (ter)polymerization to access ester-containing cryoprotective polyampholytes, which were shown to be degradable. Using a challenging… read more here.

DOI: 10.1039/c8sc02256a

Abstract: Degradable polymer prodrugs were synthesized by ‘drug-initiated’ nitroxide-mediated radical ring-opening copolymerization and led to either nanoparticles or soluble prodrugs with adjustable cytotoxicity on two different cancer cell lines. read more here.

DOI: 10.1039/c9py01103j

Abstract: 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. read more here.

DOI: 10.1039/d2sc06040j

Abstract: We present the synthesis, characterization and radical ring-opening polymerization (rROP) capabilities of thionoisochromanone (TIC), a fungi-derivable thionolactone. TIC is the first reported six-membered thionolactone to readily homopolymerize under free radical conditions without the presence of… read more here.
