“…Previous studies have shown that AGET, ATRP and other polymerisation systems containing reducing components have a certain ability to endure oxygen. [47][48][49] Cu (0) is a good reductant which will react with oxygen, so we wonder whether the present system can still proceed in the presence of oxygen, since much Cu(0) will be produced in the disproportionation process.…”

In this paper, novel star glycopolymers were synthesized via Cu(0)-mediated radical polymerisation at ambient temperature. The reaction was fast with little star-star coupling. Moreover, star glycopolymers can be obtained without removing oxygen from the polymerisation mixture. The effects of solvent and the ratio of initiator/catalyst/ligand on polymerisation were investigated, and the optimal conditions for the synthesis of star glycopolymer were determined. In addition, the binding ability between synthesised glycopolymers and concanavalin A (ConA) was studied using a turbidity test and quartz crystal microbalance-dissipation (QCM-D). Compared with linear glycopolymers, star glycopolymers showed higher binding ability to specific lectins and the strongest binding was obtained when the molecular weight was medium.

“…[26,27] These methods encompass, e.g., initiators for continuous activator regeneration (ICAR) ATRP, [28] activators regenerated by electron transfer (ARGET) ATRP [28][29][30] and activators generated by electron transfer (AGET) ATRP. [31][32][33][34] Common to all three approaches is the activation of the catalyst via a reducing agent or an organic radical initiator. In ARGET and ICAR ATRP the regeneration of the catalyst after consumption is established by adding an excess of these reagents.…”

Block copolymers of 1H,1H,2H,2H‐perfluorodecyl acrylate (AC8) were obtained from ARGET ATRP. To obtain block copolymers of low dispersity the PAC8 block was synthesized in anisole with a CuBr2/PMDETA catalyst in the presence of tin(II) 2‐ethylhexanoate as a reducing agent. The PAC8 block was subsequently used as macroinitiator for copolymerization with butyl and tert‐butyl acrylate carried out in scCO2. To achieve catalyst solubility in CO2 two fluorinated ligands were employed. The formation of block copolymers was confirmed by size exclusion chromatography and DSC. magnified image

In this work, reverse atom transfer radical copolymerization of styrene and acrylonitrile was investigated at 65°C in ionic liquid microemulsion using 2,2'-azobis(isobutyronitrile) (AIBN) as initiator, FeCl 3 ·6H 2 O/succnic acid as catalyst complex, and hexadecyl trimethyl ammonium bromide as surfactant. The copolymers of styrene and acrylonitrile (SAN) with predetermined molecular weights and narrow molecular weight distribution were obtained. Results showed that the polymerization proceeded in a controlled/'living' process in which the molecular weight of SAN increased with increasing the monomer conversion. The size of the resulting SAN particle was investigated. The monomer reactivity ratios increased with increasing the molar ratio of acrylonitrile to styrene. The obtained polymer was characterized by 13 C nuclear magnetic resonance and gel permeation chromatography. The living characteristics were demonstrated by chain extension experiment.
