Controlled/"Living" Radical Polymerization. Halogen Atom Transfer Radical Polymerization Promoted by a Cu(I)/Cu(II) Redox Process

Abstract

ABSTRACT: An extension of atom transfer radical addition, ATRA, to atom transfer radical polymeri-zation, ATRP, provided a new and efficient way to conduct controlled/"living " radical polymerization. By using a simple alkyl halide, R-X (X = C1 and Br), as an initiator and a transition metal species complexed by suitable ligand(s), Mtfl/LX, e.g., CuX/2,2'-bipyridine, as a catalyst, ATRP of vinyl monomers such as styrenes and (meth)acrylates proceeded in a living fashion, yielding polymers with degrees of polymer-ization predetermined by A[Ml/[Ilo up to M, RZ lo5 and low polydispersities, 1.1 < M J M, < 1.5. The participation of free radical intermediates was supported by analysis of the end groups and the stereochemistry of the polymerization. The general principle and the mechanism of ATRP are elucidated. Various factors affecting the ATRP process are discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
