Developing new tools to combine different polymerization techniques significantly extends the possibilities in terms of polymer design. Here, we report on a radical process abbreviated ESARA that creates a bridge between two controlled radical polymerization (CRP) techniques, nitroxide-mediated polymerization (NMP) and reversible addition-fragmentation chain transfer polymerization (RAFT). Proof of concept was first obtained with low mol. weight compounds Alkoxyamine and thiocarbonylthio control agents were shown to exchange their resp. substituents in selected exptl. conditions, opening the way for the synthesis of new original control agents. The ESARA process was then implemented at the macromol. level. Polystyryl macroalkoxyamines were converted to the corresponding polystyryl macroRAFT agents using thiocarbonylthio compounds In addition, polystyryl macroRAFT agents were converted back to polystyryl macroalkoxyamine after reaction with an alkoxyamine. The bridge created between the two CRP techniques offers an access to a large number of well-defined polymer architectures such as block copolymers that would be difficult to obtain by only one technique. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Related Products of 27249-90-7).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Related Products of 27249-90-7
