This paper provides a third update to the review of reversible deactivation radical polymerization (RDRP) achieved with thiocarbonylthio compounds (ZC(¼S)SR) by a mechanism of reversible addition-fragmentation chain transfer ( Chem. 2009Chem. , 62, 1402. This review cites over 700 publications that appeared during the period mid 2009 to early 2012 covering various aspects of RAFT polymerization which include reagent synthesis and properties, kinetics and mechanism of polymerization, novel polymer syntheses, and a diverse range of applications. This period has witnessed further significant developments, particularly in the areas of novel RAFT agents, techniques for end-group transformation, the production of micro/nanoparticles and modified surfaces, and biopolymer conjugates both for therapeutic and diagnostic applications.

“…1, polymer precipitated out of solution at the Cu(0) wire surface, with about 40 wt.% of the initial HEA consumed by formation of insoluble gel during the 120 min reaction, as estimated by the mass of material. Because of the significant amount of gel formation, the HEA conversion and M n,HMR calculations based on 1 H-NMR spectra are not reliable. Table 1 reports the SEC-measured M n values of the soluble polymer fraction as a function of reaction time, with high dispersity found throughout the reaction.…”

Aqueous copper(0) mediated reversible deactivation radical polymerization of 2-hydroxyethyl acrylate

2015

View full text Add to dashboard Cite

a Reversible deactivation radical polymerization (RDRP) of 2-hydroxyethyl acrylate in D2O with Cu(0) wire mediation and with two-step Cu(0) in situ mediation was investigated. The concentration of active species on the Cu(0) surface, which was influenced by Cu(0) type (wire or particle), polymer chain length, and activator and deactivator concentration, was the key factor in understanding the formation of insoluble gel with Cu(0) wire and/or a high molecular weight (MW) shoulder observed in the polymer molar mass distributions (MMDs). The influences of temperature, residual oxygen (dependent on the transfer procedure used to add reagents), and NaBr addition were also studied. The insights gained were used to produce P(HEA) with high molar mass [target chain length (TCL) =400, 87% conversion, Đ=1.16] using only ca. 250 ppm copper at room temperature, the first reported preparation of high MW P(HEA) with a low Đ using such a low copper catalyst concentration in a purely aqueous environment.

“…Therefore, these polymers bearing hydroxyl functional groups allow the preparation of multiple and complex structures and materials with many different uses. [7] Well-defined polymers based on HEA and HEMA have been mainly synthesized by controlled/living radical polymerization. This is, at least partially, because ionic polymerizations fail due to interactions of the hydroxyl groups with both the catalyst and the initiator.…”
