Coordinative chain transfer polymerization (CCTP) has opened a new path for the development of novel products like olefin block copolymers and chain-end functional polyolefins. However, conflicting results are frequently reported on the catalyst performance including activity and comonomer selectivity under CCTP conditions. Here we have selected two catalysts including rac-ethylenebis(1-η5-inde...

a moment equations method was performed to study the reversible chain transfer catalyzed polymerization (rtcp) of styrene in 80°c. to do this, a kinetic scheme containing conventional free radical polymerization reactions and equilibrium reactions of rtcp was assumed. after obtaining mass balance equations, three moment equations were defined for free and dormant radicals and dead chains. monom...

Abstract Chain polymerizations are defined as chain reactions where the propagation steps occur by reaction between monomer(s) and active site(s) on polymer chains with regeneration of at each step. Many forms polymerization can be distinguished according to mechanism step (e.g., cyclopolymerization – when rings formed, condensative is a condensation reaction, group-transfer polymerization, pol...

Reversible Addition–Fragmentation chain Transfer (RAFT) polymerization has emerged as one of the most versatile reversible deactivation radical polymerization techniques and is capable of polymerizing a wide range of monomers under various conditions. One of the most important factors governing the success of a RAFT polymerization is the fraction of living chains at the end of the reaction, whi...

Polymeric vesicles with tertiary amine and epoxy functional groups were fabricated via the reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of 2-(diisopropylamino) ethyl methacrylate (DIPEMA) glycidyl (GlyMA) in an ethanol-water mixture by using poly (ethylene oxide)-4-(4-Cyanopentanoic acid) dithiobenzoate (mPEG45-CPADB) as macro-chain-transfer agent (macro-CTA...

Front Cover: In article 2300119 by Prokopios Georgopanos and co-workers, thermoresponsive particles from poly(N,N-dimethylacrylamide-co-N-isopropylacrylamide)-b-polystyrene are synthesized via reversible addition-fragmentation chain transfer (RAFT) emulsion polymerization analyzed dynamic light scattering (DLS) transmission electron microscopy (TEM). The scale-up of the synthesis requires sever...
