Abstract Organocatalytic atom transfer radical polymerization (O-ATRP) is recently emerging as an appealing method for the synthesis of metal-free polymer materials with well-defined microstructures and architectures. However, development highly effective catalysts that can be employed at a practical low loading are still challenging task. Herein, we introduce catalyst design logic based on het...

We developed dinuclear molybdenum cluster-catalyzed radical addition and polymerization reactions by tuning the redox potential of the Mo(2) core. A 2,4,6-triisopropylbenzoate-supported Mo(2) complex acts as a catalyst for radical addition reactions of polyhaloalkanes to 1-alkenes and cyclopentene, while amidinate- and guanidinate-supported Mo(2) clusters are effective catalysts for the radical...

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...

Hydrocarhon free radicals play a very important role in many thermalchemistry processes. including combustion. petroleum and coal coking, coal liquefaction and pyrolysis. oil shale retorting, thermal stability of fuels as well as free rddiciij polymerization. To obtain heats of formation (AH",) of the radicals is very essential for the fundamental understanding of thermal chemistry and mechanis...

Herein, a straightforward synthesis of novel class polymers, that is, poly(N-(4-vinylphenyl)sulfonamide)s, and their monomers is reported. A set with varying electron densities, fine-tuned by different substituents on the aromatic sulfonamide moiety, polymerized free radical polymerization featuring low molar masses (2300 ≤ Mn 3200 g mol−1) dispersities (1.15 Đ 1.47). Further, post-polymerizati...
