Back Cover: In article number 2000765 by San H. Thang, Anchao Feng, Zhao Wang, and co-workers, a series of well-defi ned CO2-responsive statistical, gradient block copolymer nano-objects are synthesized through batch, semi-batch stepwise reversible addition-fragmentation chain transfer (RAFT) polymerization. aqueous solution, the copolymers can self-assemble into various aggregates before CO2 s...

A dithiocarbamate chain transfer agent (CTA) based on Z-group substituted with a diphenyl amine (–NPh2) moiety is selected for the synthesis of statistical and diblock copolymers ethylene vinyl acetate via reversible addition–fragmentation polymerization. Benefiting from good growth control polyethylene (PE), poly(vinyl acetate) (PVAc), poly(ethylene-co-vinyl (EVA) achieved this CTA, linear typ...

Small-angle neutron scattering (SANS) studies of reversible addition-fragmentation chain transfer (RAFT) microemulsion polymerizations of butyl acrylate and 2-ethylhexyl acrylate with the RAFT agent methyl2-(O-ethylxanthyl)propionate (MOEP) allow the observed rate retardation to be attributed to slow fragmentation of the macro-RAFT radical. Microemulsion polymerization allows the RAFT mechanism...

The review describes the development of batch solid phase extraction procedures based on dispersive (micro)solid with molecularly imprinted polymers (MIPs) and magnetic MIPs (MMIPs). Advantages disadvantages various for are discussed. In addition, an effort has also been made to condense information regarding MMIPs since there a great variety supports (magnetite magnetite composites carbon nano...

a variety of group 4 metal catalytic systems (c2-symmetric {ebthi}-, {sbi}-type zirconocene complexes (c2-1–4); c1-symmetric (c1-5–8) and cs-symmetric (cs-9) {cp/flu}-type zirconocene complexes; cp*2zrcl2 (cp* 2-10)), half-metallocene complexes (cpticl3, hm-11), constrained-geometry (cgc-12) titanium catalysts) and post-metallocene catalysts (dow’s ortho-metallated amido-pyridino hafnium comple...
