The preparation of liquid-filled (isooctane core) polystyrene nanocapsules by RAFT miniemulsion polymerization has been reported.[] Although good control over polymerization was obtained with both cumyl dithiobenzoate 9 and dithiophenylacetate 38, significant retardation was observed with the dithiobenzoate RAFT agent and it was proposed this prevented development of the desired core–shell morphology.

AB - A facile method to prepare cationic cobaltocenium-containing polyelectrolyte is reported. Cobaltocenium monomer with methacrylate is synthesized by copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction between 2-azidoethyl methacrylate and ethynylcobaltocenium hexafluorophosphate. Further controlled polymerization is achieved by reversible addition- fragmentation chain transfer polymerization (RAFT) by using cumyl dithiobenzoate (CDB) as a chain transfer agent. Kinetic study demonstrates the controlled/living process of polymerization. The obtained side-chain cobaltocenium-containing polymer is a metal-containing polyelectrolyte that shows characteristic redox behavior of cobaltocenium. A facile synthesis method to functional cobaltocenium-containing polyelectrolyte is reported. By using click chemistry and RAFT, the functional cationic cobaltocenium polymer is prepared from un-substituted cobaltocenium. The obtained polymer shows characteristic UV-vis absorption peaks and redox properties of the cobaltocenium group.

A PHEMA brush was formed on a poly(tetrafluoroethylene--hexafluoropropylene) (FEP) film by first carrying out surface modification with an oxygen plasma to introduce peroxide functionality. This functionality was used to initiate RAFT polymerization of HEMA in the presence of cumyl dithiobenzoate to produce FEP--(PHEMA).[]

A detailed study of the product of RAFT polymerization of MA with both cumyl dithiobenzoate and cumyl dithiophenylacetate using coupled size exclusion chromatography–electrospray ionization mass spectrometry has been carried out with a view to detecting products which might be formed by a side reaction of the intermediate radical by radical–radical termination. As in previous studies of this nature, these were not detected.[]
