Ultra-fast microwave enhanced reversible addition-fragmentation chain transfer (RAFT) polymerization: monomers to polymers in minutes.
Microwave mediated RAFT polymerization leads to ultra-fast polymerizations, whilst keeping excellent control over molecular weights and molecular weight distributions; this is the first example of such a dramatic effect of microwaves on living radical polymerization kinetics, and it shows the potential for chemists to produce very well controlled polymers in a matter of minutes.
متن کاملSynthesis of bottlebrush polymers via transfer-to and grafting-through approaches using a RAFT chain transfer agent with a ROMP-active Z-group†
A novel dithiocarbamate chain transfer agent (CTA1) with a directly polymerizable Z-group was synthesized for use in reversible addition–fragmentation chain transfer polymerization (RAFT). This CTA effectively mediated RAFT polymerization of styrenic and acrylic monomers with dispersities (Đ) < 1.08. Utilizing the polymerizable Z-group on the ω-chain end that is inherited from the RAFT process,...
متن کاملA Versatile Method To Prepare RAFT Agent Anchored Substrates and the Preparation of PMMA Grafted Nanoparticles
Well-defined polymer brushes grafted onto silica nanoparticles were prepared by reversible additionfragmentation chain transfer polymerization (RAFT). A versatile RAFT agent, 4-cyanopentanoic acid dithiobenzoate (CPDB), was attached to amino-functionalized colloidal silica nanoparticles by direct condensation of the mercaptothiazoline-activated CPDB with the surface amino groups. RAFT polymeriz...
متن کاملSynthesis of Polymeric Nanoparticles by Reversible Addition-fragmentation Chain Transfer (raft) Polymerization in Co2-induced Miniemulsion
Implementation of controlled/living radical polymerization in miniemulsion (typically with oil droplet diameter of 20-500 nm) for synthesis of well-defined, polymeric nanoparticles is of particular interest as miniemulsions possess the inherent advantage that ideally each monomer droplet is transformed into a polymer particles(Zetterlund et al., 2008). However, the high energy requirement for m...
